Question: A pump that is driven by a $7.5 mathrm{hp}$ motor takes water in at $75^{circ} mathrm{F}$ and $5 mathrm{psig}$ and discharges it at $60 mathrm{psig}$

A pump that is driven by a $7.5 \mathrm{hp}$ motor takes water in at $75^{\circ} \mathrm{F}$ and $5 \mathrm{psig}$ and discharges it at $60 \mathrm{psig}$ at a flow rate of $600 \mathrm{lb}_{\mathrm{m}} / \mathrm{min}$. If no heat is transferred between the water in the pump and the surroundings, what will be the temperature of the water leaving the pump?
