A turbocharged 6-cy, V-type diesel engine has an air consumption of 3000 kg/hr. per cylinder at rated load and speed. This air is drawn in through a filter by a centrifugal compressor directly connected to the exhaust gas turbine. The temperature of the air from the compressor is 145degC and a counterflow air cooler reduces the air temperature to 45degC before it goes to the engine suction header. Cooling water enters air cooler at 30degC and leaves at 38degC. Calculate the cooling water needed in m³/hr required to cool the total air requirement of the engine at rated load and speed
