STEP 0: Pre-Calculation Summary
Formula Used
Brake Power = (Brake Mean Effective Pressure*Stroke Length*Area of Cross Section*(Engine Speed))
BP = (Pmb*L*A*(N))
This formula uses 5 Variables
Variables Used
Brake Power - (Measured in Watt) - Brake Power is the power available at the crankshaft.
Brake Mean Effective Pressure - (Measured in Pascal) - Brake Mean Effective Pressure is a calculation of the engine cylinder pressure that would give the measured brake horsepower.
Stroke Length - (Measured in Meter) - Stroke Length is the distance travelled by the piston during each cycle.
Area of Cross Section - (Measured in Square Meter) - Area of cross section is the enclosed surface area, product of length and breadth.
Engine Speed - (Measured in Radian per Second) - Engine Speed is the speed at which the crankshaft of the engine rotates.
STEP 1: Convert Input(s) to Base Unit
Brake Mean Effective Pressure: 6.25 Kilopascal --> 6250 Pascal (Check conversion here)
Stroke Length: 8.8 Centimeter --> 0.088 Meter (Check conversion here)
Area of Cross Section: 30 Square Centimeter --> 0.003 Square Meter (Check conversion here)
Engine Speed: 4000 Revolution per Minute --> 418.879020457308 Radian per Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
BP = (Pmb*L*A*(N)) --> (6250*0.088*0.003*(418.879020457308))
Evaluating ... ...
BP = 691.150383754558
STEP 3: Convert Result to Output's Unit
691.150383754558 Watt -->0.691150383754558 Kilowatt (Check conversion here)
FINAL ANSWER
0.691150383754558 0.69115 Kilowatt <-- Brake Power

Brake Power given Mean Effective Pressure Formula

Brake Power = (Brake Mean Effective Pressure*Stroke Length*Area of Cross Section*(Engine Speed))
BP = (Pmb*L*A*(N))

What is mean effective pressure of an engine ?

Mean effective pressure is the constant pressure acting on the piston during the working stroke to do the same work as done by actual varying pressure produced during cycle.
It is the ratio of work done to the piston displacement.
Pm = work done / stroke volume .
