Specific Power Output Solution

STEP 0: Pre-Calculation Summary

Formula Used

Specific Power Output = Brake Power/Area of Cross Section
P_s = BP/A
This formula uses 3 Variables

Variables Used

Specific Power Output - (Measured in Watt) - Specific Power Output of an engine is defined as the power output per unit piston area.
Brake Power - (Measured in Watt) - Brake Power is the power available at the crankshaft.
Area of Cross Section - (Measured in Square Meter) - Area of Cross Section is the enclosed surface area, product of length and breadth.

STEP 1: Convert Input(s) to Base Unit

Brake Power: 0.55 Kilowatt --> 550 Watt (Check conversion here)
Area of Cross Section: 30 Square Centimeter --> 0.003 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_s = BP/A --> 550/0.003

Evaluating ... ...

P_s = 183333.333333333

STEP 3: Convert Result to Output's Unit

183333.333333333 Watt -->183.333333333333 Kilowatt (Check conversion here)

FINAL ANSWER

183.333333333333 ≈ 183.3333 Kilowatt <-- Specific Power Output
