Indicated Power for Single-acting Compressor Solution

STEP 0: Pre-Calculation Summary
Formula Used
Indicated Power = (Work done during Polytropic Compression*Speed in RPM)/60
PIndicated = (WPolytropic*N)/60
This formula uses 3 Variables
Variables Used
Indicated Power - (Measured in Watt) - Indicated power is all the power derived from the P-V diagram. Brake power is then the total power required to be input to the compressor to get the indicated power to the gas (for the P-V diagram).
Work done during Polytropic Compression - (Measured in Joule) - Work done during Polytropic Compression is the work done on the system during the polytropic compression of refrigerant.
Speed in RPM - Speed in RPM is the number of turns of the object divided by time, specified as revolutions per minute (rpm).
STEP 1: Convert Input(s) to Base Unit
Work done during Polytropic Compression: 8 Joule --> 8 Joule No Conversion Required
Speed in RPM: 58.5 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
PIndicated = (WPolytropic*N)/60 --> (8*58.5)/60
Evaluating ... ...
PIndicated = 7.8
STEP 3: Convert Result to Output's Unit
7.8 Watt --> No Conversion Required
FINAL ANSWER
7.8 Watt <-- Indicated Power

What is single-acting compressor?

With a single-acting compressor, the air is compressed only on the up-stroke of the piston inside the cylinder. The double-acting compressor compresses the air on both the up-stroke and the down-stroke of the piston, doubling the capacity of given cylinder size.

How to Calculate Indicated Power for Single-acting Compressor?

Indicated Power for Single-acting Compressor calculator uses Indicated Power = (Work done during Polytropic Compression*Speed in RPM)/60 to calculate the Indicated Power, The Indicated Power for Single-acting Compressor formula is defined as the power derived from the P-V diagram. Brake power is then the total power required to be input to the compressor to get the indicated power to the refrigerant (for the P-V diagram). Indicated Power is denoted by PIndicated symbol.

How to calculate Indicated Power for Single-acting Compressor using this online calculator? To use this online calculator for Indicated Power for Single-acting Compressor, enter Work done during Polytropic Compression (WPolytropic) & Speed in RPM (N) and hit the calculate button.
