$2\mathrm{.}5.$ Experimental Data Sheet

$2\mathrm{.}6$ Calculation

$2\mathrm{.}6\mathrm{.}1$ Plot the experimental data on a p$-$h diagram $($of R$-22)$ to obtain the refrigeration cycle

$2\mathrm{.}6\mathrm{.}2$ From the p$-$h diagram, determine the enthalpy values and hence calculate:

$($a$)$ The refrigeration effect,

$($b$)$ The compressor work,

$($c$)$ The heat rejected at condenser, and

$($d$)$ The coefficient of performance.

Tabulate the results obtained from your calculation.
