Input Power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Input Power = Output Power+Power Loss
P_i = P_out+P_loss
This formula uses 3 Variables

Variables Used

Total Input Power - (Measured in Watt) - Total Input Power is calculated by multiplying voltage (in volts) by current (in amps).
Output Power - (Measured in Watt) - Output Power is the power supplied by the electrical machine to the load connected across it.
Power Loss - (Measured in Watt) - Power Loss is the loss of the electrical power network supply to an end user.

STEP 1: Convert Input(s) to Base Unit

Output Power: 36.3 Watt --> 36.3 Watt No Conversion Required
Power Loss: 15.7 Watt --> 15.7 Watt No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_i = P_out+P_loss --> 36.3+15.7

Evaluating ... ...

P_i = 52

STEP 3: Convert Result to Output's Unit

52 Watt -->52 Joule per Second (Check conversion here)

FINAL ANSWER

52 Joule per Second <-- Total Input Power

Output Power given Rate of Flow through Propeller

Go Output Power = Water Density*Rate of Flow*Flow Velocity*(Absolute Velocity of Issuing Jet-Flow Velocity)

Flow Velocity given Power Lost

Go Flow Velocity = Absolute Velocity of Issuing Jet-sqrt((Power Loss/(Density of Fluid*Rate of Flow*0.5)))

Rate of Flow through Propeller

Go Rate of Flow through Propeller = (pi/8)*(Diameter of Turbine^2)*(Absolute Velocity of Issuing Jet+Flow Velocity)

Rate of Flow given Power Lost

Go Rate of Flow = Power Loss/Density of Fluid*0.5*(Absolute Velocity of Issuing Jet-Flow Velocity)^2

Power Lost

Go Power Loss = Density of Fluid*Rate of Flow*0.5*(Absolute Velocity of Issuing Jet-Flow Velocity)^2

Flow Velocity given Rate of Flow through Propeller

Go Flow Velocity = (8*Rate of Flow/(pi*Diameter of Turbine^2))-Absolute Velocity of Issuing Jet

Flow Velocity given Thrust on Propeller

Go Flow Velocity = -(Thrust Force/(Water Density*Rate of Flow))+Absolute Velocity of Issuing Jet

Diameter of Propeller given Thrust on Propeller

Go Diameter of Turbine = sqrt((4/pi)*Thrust Force/Change in Pressure)

Thrust on Propeller

Go Thrust Force = (pi/4)*(Diameter of Turbine^2)*Change in Pressure

Theoretical Propulsive Efficiency

Go Efficiency of Jet = 2/(1+(Absolute Velocity of Issuing Jet/Flow Velocity))

Flow Velocity given Theoretical Propulsive efficiency

Go Flow Velocity = Absolute Velocity of Issuing Jet/(2/Efficiency of Jet-1)

Output Power given Input Power

Go Output Power = Total Input Power-Power Loss

Power Lost given Input Power

Go Power Loss = Total Input Power-Output Power

Input Power

Go Total Input Power = Output Power+Power Loss

Input Power Formula

Total Input Power = Output Power+Power Loss
P_i = P_out+P_loss

What is Fluid Power?

Fluid power is a term describing hydraulics and pneumatics technologies. Both technologies use a fluid (liquid or gas) to transmit power from one location to another. With hydraulics, the fluid is a liquid (usually oil), whereas pneumatics uses a gas (usually compressed air).

How to Calculate Input Power?

Input Power calculator uses Total Input Power = Output Power+Power Loss to calculate the Total Input Power, The Input Power is defined as total power being generated by the propeller of the jet engine used for rotation. Total Input Power is denoted by P_i symbol.
