Specific Power Output Solution

STEP 0: Pre-Calculation Summary
Formula Used
Specific Power Output = Brake Power/Area of Cross Section
Ps = 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
Ps = BP/A --> 550/0.003
Evaluating ... ...
Ps = 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
(Calculation completed in 00.004 seconds)
