A standard vapor compression refrigeration cycle operating with a condensing temperature of $35^{\circ}C$ and an evaporating temperature of $-10^{\circ}C$ develops $15 \: kW$ of cooling. The $p-h$ diagram shows the enthalpies at various states. If the isentropic efficiency of the compressor is $0.75$, the magnitude of compressor power (in $kW$) is _________ (correct to two decimal places)
