How do you calculate the Volumetric efficiency of a hydraulic motor?

Dear friend,
Drive the motor through a pump. Supply oil to achieve a given rpm and pressure.
Some oil will come out of case drain port and some from the out put port of the motor.
Measure the out put flow of the motor and input flow to the motor.
out put by input will be the volumetric efficiency ( the loss is case drain )
( alternatively, case drain and output flow fof the motor can be measured, then output flow divided by the sum of output flow and case drain flow is the efficiency )

Can a hydraulic motor be used as helm pump?
Instead of hydraulic pumps, hydraulic gear motor does not work. Hydraulic pump hydraulic motor blade is used instead.

How much energy does a motor convert to heat?
You can calculate the quantity of energy that a motor turns into heat with either one of these equations: Heat energy = ( 1 - efficiency of the motor) x (energy input to the motor) or Heat energy = ( 1 - efficiency of the motor) x (power input to the motor) x (running time)
What is hydraulic cylinder linear and hydraulic motor?
Only the sweep is linear cylinder. Motor rotates the hydraulic oil pressure.
What is a motor vane?
It is a hydraulic motor housing containing a vane that turns the shaft when hydraulic fluid is pump through the motor.
Is the convertible top motor hydraulic or electric?
It is both, an electric motor runs a hydraulic pump.
What size hydraulic motor is needed to be equal to a 3 hp electric motor?
1 HP electric motor = 1.5 HP hydraulic motor so for a 3 HP electric motor you would need a 4.5 HP hydraulic motor. Also for your information a 1 HP hydraulic motor = 1 2/3 HP gasoline engine.
Use of a turbo in a car?
To increase power of the motor, by increasing airflow thru the motor(higher volumetric effiecency) when needed.
What is hydraulic ram servo?
A hydraulic piston is also known as a servo or a motor.
How the correlation between hydraulic motor and hydraulic pump?
Internally, they're pretty much the same. The difference is the operation expected of it - a hydraulic pump converts mechanical energy to fluid energy, whereas a hydraulic motor converts hydraulic energy to mechanical energy.
