Brake Mean Effective Pressure of 2S engines given Brake power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Brake Mean Effective Pressure = (Brake Power)/(Stroke Length*Area of Cross Section*(Engine Speed))
P_mb = (BP)/(L*A*(N))
This formula uses 5 Variables

Variables Used

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.
Brake Power - (Measured in Watt) - Brake Power is the power available at the crankshaft.
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 Power: 0.008 Kilowatt --> 8 Watt (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

P_mb = (BP)/(L*A*(N)) --> (8)/(0.088*0.003*(418.879020457308))

Evaluating ... ...

P_mb = 72.3431559545456

STEP 3: Convert Result to Output's Unit

72.3431559545456 Pascal -->0.0723431559545455 Kilopascal (Check conversion here)

FINAL ANSWER

0.0723431559545455 ≈ 0.072343 Kilopascal <-- Brake Mean Effective Pressure

(Calculation completed in 00.021 seconds)

What is brake mean effective pressure ?

The torque generated at the crankshaft is called the Brake Torque. The Mean effective pressure calculated from the Brake torque is called the Brake Mean Effective Pressure.

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 .
