Governor Power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Power = Mean Effort*Lift of Sleeve
P = P_mean*x_sleeve
This formula uses 3 Variables

Variables Used

Power - (Measured in Watt) - Power is the amount of energy liberated per second in a device.
Mean Effort - (Measured in Newton) - Mean Effort is an applied force to bring desired change to the position (push or lift) of the load.
Lift of Sleeve - (Measured in Meter) - The lift of sleeve is the vertical distance which the sleeve travels due to a change in equilibrium speed.

STEP 1: Convert Input(s) to Base Unit

Mean Effort: 15 Newton --> 15 Newton No Conversion Required
Lift of Sleeve: 0.012 Meter --> 0.012 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = P_mean*x_sleeve --> 15*0.012

Evaluating ... ...

P = 0.18

STEP 3: Convert Result to Output's Unit

0.18 Watt --> No Conversion Required

FINAL ANSWER

0.18 Watt <-- Power

(Calculation completed in 00.020 seconds)

Total Downward Force on Sleeve in Wilson-Hartnell Governor

Go Force = Mass on Sleeve*Acceleration due to Gravity+(Tension in the auxiliary spring*Distance of auxiliary spring from mid of lever)/Distance of main spring from mid point of lever

Speed of Rotation in RPM

Go Mean Equilibrium Speed in RPM = 60/(2*pi)*sqrt((tan(Angle b/w axis of radius of rotation & line OA))/Mass of Ball)

Ratio of Length of Arm to Length of Link

Go Ratio of Length of Link to Length of Arm = tan(Angle of Inclination of Link to Vertical)/tan(Angle of Inclination of Arm to Vertical)

Corresponding Radial Force Required at Each Ball for Spring Loaded Governors

Go Corresponding Radial Force Required at Each Ball = (Force Required at Sleeve to Overcome Friction*Length of sleeve arm of lever)/(2*Length of ball arm of lever)

Angle between Axis of Radius of Rotation and Line Joining Point on Curve to Origin O

Go Angle b/w axis of radius of rotation & line OA = atan(Controlling Force/Radius of Rotation if Governor is in Mid-Position)

Angle between Axis of Radius of Rotation and Line Joining Point on Curve to Origin

Go Angle b/w axis of radius of rotation & line OA = atan(Mass of Ball*Mean Equilibrium Angular Speed^2)

Mean Equilibrium Speed in RPM

Go Mean Equilibrium Speed in RPM = (Minimum equilibrium speed in r.p.m+Maximum equilibrium speed in r.p.m)/2

Mean Equilibrium Angular Speed

Go Mean Equilibrium Angular Speed = (Minimum equilibrium angular speed+Maximum equilibrium angular speed)/2

Sleeve Load for Decrease in Speed Value when Taking Friction into Account

Go Sleeve load for decrease in speed = Total load on sleeve-Force Required at Sleeve to Overcome Friction

Sleeve Load for Increase in Speed Value when Taking Friction into Account

Go Sleeve load for increase in speed = Total load on sleeve+Force Required at Sleeve to Overcome Friction

Increased Speed

Go Increased Speed = Mean Equilibrium Speed in RPM*(1+Percentage Increase in Speed)

Governor Power

Go Power = Mean Effort*Lift of Sleeve

Height of Watt Governor

Go Height of Governor = 895/(Speed in RPM^2)

Governor Power Formula

Power = Mean Effort*Lift of Sleeve
P = P_mean*x_sleeve

What is difference between governor and flywheel?

The main difference between the two is that the flywheel is always under operation when the engine is running and the operation is continuous from cycle to cycle, whereas the operation is intermittent in the case of the governor, which means it only operates when the engine does not run at its mean speed.

How to Calculate Governor Power?

Governor Power calculator uses Power = Mean Effort*Lift of Sleeve to calculate the Power, The Governor power formula is defined as the work done at the sleeve of the governor for a percentage change in speed. Power is denoted by P symbol.

How to calculate Governor Power using this online calculator? To use this online calculator for Governor Power, enter Mean Effort (P_mean) & Lift of Sleeve (x_sleeve) and hit the calculate button. Here is how the Governor Power calculation can be explained with given input values -> 0.18 = 15*0.012.

FAQ

What is Governor Power?

The Governor power formula is defined as the work done at the sleeve of the governor for a percentage change in speed and is represented as P = P_mean*x_sleeve or Power = Mean Effort*Lift of Sleeve. Mean Effort is an applied force to bring desired change to the position (push or lift) of the load & The lift of sleeve is the vertical distance which the sleeve travels due to a change in equilibrium speed.

How to calculate Governor Power?

The Governor power formula is defined as the work done at the sleeve of the governor for a percentage change in speed is calculated using Power = Mean Effort*Lift of Sleeve. To calculate Governor Power, you need Mean Effort (P_mean) & Lift of Sleeve (x_sleeve). With our tool, you need to enter the respective value for Mean Effort & Lift of Sleeve and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
