This calculator evaluates various ratios and efficiency for Refrigerators.

Inputs



Q(1)
:150.00J



Q(2)
:200.00J



T(1)
:23.00degC



T(2)
:30.00


Coefficient of performance:


β=Heat ExtractedWtotal=Q2Wtotal=Q2Q1Q2=T2T1T2\beta=\frac{Heat\ Extracted}{W_{total}}=\frac{Q_2}{W_{total}}=\frac{Q_2}{Q_1-Q_2}=\frac{T_2}{T_1-T_2}

Output



W
:-50.00


Q1=Q2+WQ_1=Q_2+W


β (eqn 1)
:-4.00


βequation 1=Q2Wtotal\beta_{equation\ 1}=\frac{Q_2}{W_{total}}


β (eqn 2)
:-4.00


βequation 2=Q2Q1Q2\beta_{equation\ 2}=\frac{Q_2}{Q_1-Q_2}


β (eqn 3)
:-4.29


βequation 3=T2T1T2\beta_{equation\ 3}=\frac{T_2}{T_1-T_2}

The following are the variables for the equations
