A steam turbine discharges \(5000 \mathrm{~kg} / \mathrm{h}\) of steam at \(40^{\circ} \mathrm{C}\) and 0.85 dry. The air leakage in the condenser is \(15 \mathrm{~kg} / \mathrm{h}\). The temperature at the suction of air pump is \(32^{\circ} \mathrm{C}\) and the temperature of condensate is \(35^{\circ} \mathrm{C}\). Find (a) vacuum gauge reading, (b) capacity of air pump, (c) loss of condensate in \(\mathrm{kg} / \mathrm{h}\), and (d) quantity of cooling water if its temperature rise is limited to \(10^{\circ} \mathrm{C}\).
