How do you calculate effort the machine of velocity ratio 5 and efficiency 60 percent calculate the effort required to lift a load of 300N?
efficiency=mechanical advantage/velocity ratio mechanical advantage=load/effort use this formula, ans:100N
How you calculate the dynamic pressure of fan?
Dynamic pressure of air = 0.5 * density * velocity of air = Pascal Where: Density = kg / cubic meter Velocity of air = m / s
Bernoullis principle about air velocity and pressure?
velocity and pressure have inverse relation. when velocity increases then pressure at that point decrease and vice versa.
What is total energy line?
The Hydraulic Grade LineThe Hydraulic Grade Line is a line representing the total head available to the fluid - minus the velocity head and can be expressed as:HGL = p / γ + h (4)whereHGL = Hydraulic Grade LineThe hydraulic grade line lies one velocity head below the the energy line.The Hydraulic Grade Line is a line representing the total head available to the fluid - minus the velocity head and can be expressed as:HGL = p / γ + h (4)whereHGL = Hydraulic Grade LineThe hydraulic grade line lies one velocity head below the the energy line.
How do you calculate satic pressure?
Consists of the pressure the air exerts in the direction of flow (Velocity Pressure) plus the pressure air exerts perpendicular to the plenum or container through which the air moves. (static pressure) In other words: PT = PV + PS PT = Total Pressure PV = Velocity Pressure PS = Static Pressure http://www.refrigeration-engineer.com/forums/archive/index.php/t-14342.html

What is the difference between the hydraulic grade line and the energy line?
Hydraulic grade line is sum of Datum + Pressure Head Energy grade line is sum of Datum + Pressure Head + Velocity Head

What is hydraulic head in reservoir engineering?
Hydraulic head is related to the amount of energy present in a hydraulic system. Hydraulic head is composed of three components: elevation head, pressure head, and velocity head. As water loses one component of its hydraulic head, the other components increase. For example: water that falls 10 feet loses 10 feet of elevation head and gains 10 feet of velocity head. The only way a hydraulic system can lose hydraulic head is through head loss due to friction.
What is the point of using a hydraulic table?
The point of using a hydraulic is quite simple, people use it to measure and estimate velocity of water passing between at least 2 points. The way to calculate the velocity and therefore have a reason to have a hydraulic table is using hydraulic conductivity, perosity and hydraulic gradient. A different kind of hydraulic table is one that is used to move heavy machinery around shop floors or in workshop style buildings, commonly used because of the strength and the manoeuvrability to move these heavy objects without the use of a bigger machine to move it.
What is the difference between hydraulic grade line and energy grade lines?
Energy gradient line refers to total energy excluding the losses due to flow. ie) Datum Head + Pressure Head + Velocity Head Hydraulic gradient line refers to the line joining upper and lower water surface levels excluding losses and velocity head. ie) Datum Head + Pressure Head
Can you calculate pipe diameter if you have pressure head and discharge flow?
Static pressure is .434 X height Example 10 ft x .434 4.34 PSI to prove take 2.31 PSI x 4.34 To find FORCE to need to calculate the diameter of the piping and the height and then the weight of the water inside the pipe
Pressure is equal to 3 into force into velocity square divided by phi square into time square?
I am not sure what you are trying to calculate. Pressure is defined as force divided by area.

What is propulsion efficiency?
It is efficiency of the propelling device in converting the applied torque into useful thrust. In an IDEAL propeller the freestream velocity and the slipstream velocity should be same. The higher the exhaust/slip stream velocity, higher is the wasted kinetic energy. Thus turbojet engine has lower propulsive efficiency and turbo-prop engine has higher propulsive efficiency.
