Pls. Answer thank you! A turbo-charged, 16 cylinder, Vee-type diesel engine has an air consumption of 3,000 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 135°C and a counter flow air cooler reduces the air temperature to 45°C before it goes to the engine suction header. Cooling water enters air cooler at 30°C and leaves at 40°C. Calculate the log mean temperature difference in oC.
