Compressor work Solution

Follow our step by step solution on how to calculate Compressor work?

FIRST Step Consider the formula

W c = h 2 - h 1

Next Step Substitute values of Variables

∴

W c = 548.5KJ - 387.6KJ

Next Step Convert Units

∴

W c = 548500J - 387600J

Next Step Prepare to Evaluate

∴

W c = 548500 - 387600

Next Step Evaluate

∴

W c = 160900J

LAST Step Convert to Output's Unit

∴

W c = 160.9KJ

How to Evaluate Compressor work?

Compressor work evaluator uses Compressor Work = Enthalpy at Exit of Compressor-Enthalpy at Compressor Inlet to evaluate the Compressor Work, Compressor Work refers to the energy required to compress a gas within a compressor. This formula calculates the compressor work by determining the difference between the enthalpy at the exit and the enthalpy at the inlet of the compressor. Compressor Work is denoted by W_c symbol.

How to evaluate Compressor work using this online evaluator? To use this online evaluator for Compressor work, enter Enthalpy at Exit of Compressor (h₂) & Enthalpy at Compressor Inlet (h₁) and hit the calculate button.

FAQs on Compressor work

What is the formula to find Compressor work?

The formula of Compressor work is expressed as Compressor Work = Enthalpy at Exit of Compressor-Enthalpy at Compressor Inlet. Here is an example- 0.1609 = 548500-387600.

How to calculate Compressor work?

With Enthalpy at Exit of Compressor (h₂) & Enthalpy at Compressor Inlet (h₁) we can find Compressor work using the formula - Compressor Work = Enthalpy at Exit of Compressor-Enthalpy at Compressor Inlet.

What are the other ways to Calculate Compressor Work?
