A 110 kW steam engine has a steam consumption of 9.5 kg per kWh. The exhaust steam enters the condenser dry saturated at 0.15 bar (h_{g} = 2598.3 kJ/kg). The condensate leaves at 35 °C (h = 146.6 kJ/kg). The cooling water enters at 18 °C and leaves at 34 °C (c_{p} = 4.187 kJ/kg·K). Estimate the quantity of cooling water required (answer in kg/h).
