Stainless

reply: want to know steel grades other than stainless against corrosion

More efforts were put in to avoid collisions such as detectors like sonars and radars, more lifeboats, and even emergency escape plans

Because quite a lot of the energy used by a combustion engine gets turned into heat whether we want it or not, so a cooling system is needed to keep the engine from overheating.

DTSI engines are normal four stroke engines but use Two Spark plugs in place of one for better combustion of compressed fuel. the two spark plugs are located at the two opposite ends of the cylinder. this particular orientation of the spark plugs provide better and faster combustion,as in the single spark engine based design the flame has to travel the whole combustion chamber but in this case the flame travels from both direction so the combustion time is smaller.

I am a Coordinator at an inspection company for the Port of Houston. As far as I have experience in this, a heel is product that is below the roof level (if there is one) in a storage tank. Water heel probably just refers to the amount of water in the product at the bottom of the tank, as water is usually heavier than most products.

HECK NO the globe pattern offers the most pressure drop because of friction losses

Yes, because if a car is really really long that means that it's really heavy. Which also means that it will move slower than a really short car because there wouldn't be as much weight to carry.

p1=power of 1st crane

p2=power of 2nd crane

p1= 2 p2

{But power = Velocity * Force

weight of both steel is same so force is same for both

p1=2p2

V1 * F=2( V2 * F)

V1 = 2 V2

therfore

velocity of 1st steel moving up is 2 times that of the 2nd steel bar moving up

Or the cranes are set at different angles - bam2

Knots one nautical mile per hour there are 1 1/8 of a nautical mile in a statute mile

Originally measured by throwing a piece of wood attached to a piece of rope over the back of a boat and counting how many knots went past in a given time. These days it is more normally measured by: a/ using a pitot static tube which measure difference in pressure and uses bernoulli's equation (enter into wikipedia as is easier to read) to find the velocity. b/ Some form of propeller (technically impeller) which is suspended under the boat. The passing water turns, the speed of rotation is measurred and this gives you the speed of the boat. c/Using ultrasonics to measure the speed that small bubbles of air in the water passing under the boat go past.

for example : if we take a size of diameter 480mm fabricated pipe of wall thickness 3mm from this we going make a elbow by formula

CMof Circle X required degree by 360 X 2 X no .of cut needed

= 1520 X 90 / 360 X 2 X 3

= 64mm

make a divde four lines on pipe

mark of line of half of diameter = 220mm in two lines next to next parallel

mark 6.4 cm by one half to another half

on both lines

then u make cut it

u will get elbow

This time is needed for just starting the spare feed pump...

Lapping is a grinding process.

It is done to remove high spots and to create a good seal between two surfaces.

A typical example would be lapping valves in an auto engine

I assume you are talking about removing trapped air from the cooling system. Park uphill or jack up the front of the vehicle. Remove the radiator cap, turn heater control to hot, and start the engine. Keep the coolant level full, while the engine runs. Watch for air bubbles escaping from the radiator. When you see none, all the air is purged. It may also have a Schroeder valve somewhere on the cooling system at the highest point that can be used to purge air.

They are both lever actions, in a way. It's a question of mechanics. Lever action rifles fell out of favor for a variety of reasons. Difficult to fire prone (lever travel), tubular magazines (blunt lead bullets only), loss of sight picture, I'm sure people can add their favorite. Pump actions weren't very popular for rifles for many of the same reasons. Tubular magazines aren't hazardous for shotguns because of the wide, blunt, plastic ends don't pose much hazard of igniting the round in front of it. The best shotguns in the world, and the best rifles for that matter, aren't lever action or pump, they are bolt or dual barrel.

For firepower - Semi-auto gas or recoil w/ spring return

For accuracy - Bolt/break action

For a civilian compromise - lever action/pump

I've fired both. For a shotgun, fired at an angle from a standing position, the pump is more ergonomic than the lever. For a rifle, standing on a more horizontal plane, it comes down to preference.

Usually, no.

Most of the time, the pilot or crew determine the required amount of fuel for a specific flight plan. They also carry extra fuel in case aircraft has to be diverted, heavy traffic, or changes in route. The idea behind it is that, in order to reduce fuel consumption, the plane has to be as light as possible, so the less fuel the plane is carrying, the better. The extra is there for safety. Rarely is fuel wasted during normal flights, and planes can land with a surplus.

In emergency procedures, it is a different story. If a commercial or military aircraft has an engine failure during takeoff, if the situation is stabilized, the pilot will then circle the airport getting rid of fuel if it is safe to do so. This is done so that in the event of an emergency landing, there is less fuel to ignite or cause an explosion.

It is the alarm that give the status of the person in unattendent engine room.

yes low pressure in tank and high pressure on driver side before tansfercase but after fuel filter. if you follow the fuel line from the fuel filter backside you'll run right in to it

The turbine heat rate of a steam turbogenerato is the ratio of thermal input: power generated. It is often expressed in kJ/kWh. The efficiency of the turbogenerator is simply calculated from this.

The plant heat rate is the ratio of fuel energy into the plant: power generated. It is greater than the turbine heat rate, because not all of the fuel's thermal energy can be captured by the boiler, and also power station services such as fuel handling, flue gas cleaning etc consume power. Consequently, more fuel is needed for each unit of useful net power produced. Plant heat rate is often expressed in kJ/kWh or Btu/kWh.

The fuel energy input used in the plant heat rate calculation may be on a higher heating value (HHV) or a lower heating value (LHV) basis, and the plant power output, although usually on a net (net of plant own consumption) is sometimes on the basis of that at the generator terminals. Whatever is used should be made clear, but it often is not.

Inefficiencies in a mechanical device related to parts rubbing together such that kinetic energy is turned into heat energy.

no,because boat uses hydraulic oil of less viscosity.
