STEP 0: Pre-Calculation Summary

Formula Used

Work Done = Enthalpy of the vapour refrigerant at T2-Enthalpy of the Vapour Refrigerant at T1
w = h₂-h₁
This formula uses 3 Variables

Variables Used

Work Done - (Measured in Joule) - Work done by/on a system is energy transferred by/to the system to/from its surroundings.
Enthalpy of the vapour refrigerant at T2 - (Measured in Joule per Kilogram) - Enthalpy of the vapour refrigerant at T2, i.e at the discharge of the compressor.
Enthalpy of the Vapour Refrigerant at T1 - (Measured in Joule per Kilogram) - Enthalpy of the vapour refrigerant at T1, i.e at the suction of the compressor.

STEP 1: Convert Input(s) to Base Unit

Enthalpy of the vapour refrigerant at T2: 280 Kilojoule per Kilogram --> 280000 Joule per Kilogram (Check conversion here)
Enthalpy of the Vapour Refrigerant at T1: 260 Kilojoule per Kilogram --> 260000 Joule per Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

w = h₂-h₁ --> 280000-260000

Evaluating ... ...
