Hydraulics

there isn't a measurment for hydraulic radius as far as i know and if you g on any website about it it doesnt have any measurements at the end of it.

Josh (A level geography student)

hydraulic radius has a unit as it is the ratio of c/s area to the wetted perimeter i. e.

A/P so unit of length............

Assume a small piston (one square inch area) applies a weight of 1 lbs. to a confined hydraulic fluid. That provides a pressure of 1 lbs. per square inch throughout the fluid. If another larger piston with an area of 10 square inches is in contact with the fluid, that piston will feel a force of 1 lbs/square inch x 10 square inches = 10 lbs. So we can apply 1 lbs. to the small piston and get 10 lbs.

Am not a 100% sure about this answer but yes it does hold some water in it, the portland cement majorly has its use in well aerated places i.e its mainly used for construction above sea or simply iits used where cement can dry in air

but the hydraulic has properties enabling it to harden properly under water. and thats where its mostly used or in places where water really comes around.

no. motors POWER hydrolic pumps. hydrolic pumps cannot function at the fast rate needed to generate energy as motors do.

Answer 2

There is not necessarily any need for a hydraulic - or any other - motor to function at a fast rate, as you put it. A hydarulic pump may need to only turn at say 1 rpm and at this speed send out enough oil to drive a hydraulic motor. Then main thing to consider is what type of pump are we talking about? A gear type oil pumo my well not work at very low speeds, but a piston type pump will work very slowly if needed.

excess pressure would be dumped to tank via the relief valve and nothing would go nowhere hopefully. Otherwise you would bend your hydraulic cylinder rod , or sheer the shaft on your motor .

Not sure if I know what "giant machines" are, but I can make a comparison with Airplanes. Some large aircraft use pulleys and cables to work the flight controls and the newer ones use hydraulics or electrical servos. The cables have an advantage in that they are less complicated than hydraulic controls. Hydraulics have to have a reservoir, a pump, and usually high pressure lines as well as a return line. This requires a lot of maintenance and present more problems if the hydraulic lines required for large vehicles. The larger the vehicle, the more hydraulic oil to fill the lines. Modern military jets and the A380 use smaller hydraulic lines pressurized at 5000psi, which reduces the required volume of oil. Of course, a system pressurized at 5000psi seems to present more problems than a 3000 psi. Now, the cons of the pulley and cable is that this does not apply as much force as a hydraulic system. Also, for long cable runs and complicated controls, the cables require a lot of rigging and adjustment and checking the cable for damages from wear. Did that help??

Hydraulic fluid could be used in two locations on your 1993 saturn. your brake system is of course Hydraulic, in this case, the easiest way to change the fluid is to obtain a vacuum brake bleeder kit from your local parts store. you will need to loosen each bleeder screw on all 4 wheels and attach the vacuum bleeder. keep an eye on the fluid level in the master cylinder so it doesnt get too low. 1 large bottle of brake fluid is enough to do an entire vehicle. If you are talking about the clutch fluid, which is also hydraulic, there is no method of changing the fluid. the unit is sealed and offers no bleeder.

torque wrench Not with a torque wrench ! Obtain your proper specs (clearance and sequence at TDC for each corresponding valve) set the valves using the specs obtained and the proper thickness gauge .Tighten each rocker to valve clearance until you have a slight drag on your gauge between the rocker and valve.

To adjust hydraulic lifters with the engine off, turn the crankshaft until the lifter is on the camshaft base circle (not the lobe). The valve must be fully closed. Loosen the adjusting nut until you can wiggle the pushrod up and down. Then slowly tighten the rocker until all play is out of the valve train (cannot wiggle pushrod). Repeat the adjusting procedure on the other rockers. To adjust hydraulic lifters with the engine running, install a special oil shroud or some other device for catching oil spray off the rocker. Start and run the engine until it reaches operating temperature. Tighten all rockers until they are quiet. One at a time, loosen a rocker until it clatters. Then tighten the rocker slowly until it quiets down. This is zero valve lash.

Assuming you have checked the hydraulic fluid and it's OK, you could look into replacing the seals on the compression cylinder, but with jacks as inexpensive as they are these days, it would be easier and maybe even cheaper to replace the jack. I routinely see two-ton jacks on sale at automotive stores for $20-30. just check the rubber seling at bucket's bottom of the ram and plunger they wear of.f

The best way to bleed the system is to make sure the pedal is up off the floor, and the resevior is full, remove the slave from the trans, open the bleeder screw push the rod into the slave, close the screw, let the rod move back out slowley,,, repeat this until the rod is feels solid. Now open the bleeder screw and slide the slave into the trans all the way, then close bleeder screw and install the pin. top of fluid....

Take a tube, put a piston in it, seal off both ends of the tube, and use a liquid, or gas to put pressure in and remove pressure from the tube. As the fluid or gas goes in the tube, the pressure pushes the piston out. As the pressure is released, the piston can recede.

the pump supply's the pressure, the resivoir supply's the fluid, the valve dirercts the fluid into the cylinder, to extend or retract the cylinder.

How do you put oil in my Ritter motor chair

It may just need to have some oil added to it, they do lose some over time. There should be either a rubber plug or a screw in plug toward the top of the cylinder on the side. If that is not the problem, it has to be rebuilt, new seal put into it. If it is a name brand, rebuild kits are sometimes available. Some off brand or import ones just have to be replaced.

it maintains a constant speed under varing load

The hydraulic lift was invented by Leon Edoux.

The principal is called Pascal's Principle.

Pascal's principle states that a pressure applied to an enclosed fluid is transmitted everywhere in the fluid. Hence, if a pressure is applied to one side of an enclosed fluid, all the other walls containing the fluid feel the same pressure. The pressure is transmitted without being diminished.

Fluid generally refers to either a liquid or a gas. If a pressure is applied to a compressible gas, Pascal's principle still applies, but the volume of the gas will change. For Pascal's principle to be useful to hydraulics, the fluid should be an incompressible liquid, which will transmit the applied pressure without changing its volume.

No, because it is not compund substance

hydraulics uses the principle of hydrostatic pressure to work

A pump that has more than one impeller. improve more pressure

Hydraulics are typically measured in pounds per square inch, which is a measurement of pressure, or force exerted with respect to area. To calculate the force used, multiply the pressure measurement by the area measurement in inches. This will give you the force in pounds, then convert that to tons.

mechanical and hydraulic are two different power transmission medium.

in mechanical brakes solid links or levers are used to achieve the required braking.

in hydraulic brakes there are no links, here the braking is achieved by the hydraulic fluid, the hydraulic system in which the force applied at the brake pedal is multiplied several times to achieve the requied braking.
