An oil cooler for a large diesel engine is to cool engine oil from 60 to 45 °C, using seawater at an inlet temperature of 20 °C with a temperature rise of 15 °C. The design heat load is 140 kW, and the mean overall heat transfer coefficient based on the outer surface area of the tubes us 70 W/m2°C. Calculate the heat transfer surface area for single pass (a)- counter flow and (b)- parallel flow arrangements.

A double-pipe heat exchanger is designed as an engine oil cooler. The flow rate of oil is 5 kg/s, and it will be cooled from 60°C to 40°C through annulus (ID = 0.10226 m, OD = 0.1143 m). Sea water flows through the tubes (ID = 0.02664 m, OD = 0.03340 m) and is heated from 10°C to 30°C. The number of bare tubes in the annulus is 3, and the length of the hairpin is 3 m. Assume that...

Engine oil (raffinate) with a flow rate of 5 kg/s will be cooled from 60°C to 40°C by sea water at 20°C in a double-pipe heat exchanger. The water flows through the inner tube, whose outlet is heated to 30°C. The inner tube outside and inside diameters are do = 1.315 in. (= 0.0334 m) and di = 1.049 in. (= 0.02664 m), respectively. For the annulus, Do = 4.5 in. (= 0.1143 m) and Di = 4.206 in. (=...

A diesel engine intakes atmospheric air at 60°F and adds 800 Btu/lbm of energy. If the maximum pressure is 1200 psia, calculate: (a) the cutoff ratio, rc ; (b) the thermal efficiency, ? ; (c) the power output, in hp, for an airflow of 0.2 lbm/sec. [Hints: Follow the Diesel cycle diagram! For ?, you will need the compression ratio.]

1. Engine oil (cp = 2100 J/kg-°C) is to be heated from 20 °C to 60 °C at a rate of 0.3 kg/s in a 2-cmdiameter thin-walled copper tube by condensing steam outside at a temperature of 130 °C (hfg = 2174 kJ/kg). a. For an overall heat transfer coefficient of 650 W/m2 -°C, determine the rate of heat transfer and the length of tube required to achieve it. Determine also the rate of steam condensation, in kgsteam/sec. (Ans: 25.2...

A counterflow, concentric tube heat exchanger is used to cool the lubricating oil for a large industrial gas turbine engine. The flow rate of cooling water through the inner tube (Di = 25 mm) is 0.2 kg/s, while the flow rate of oil through the outer annulus (Do = 45 mm) is 0.1 kg/s. The oil and water enter at temperatures of 100 and 30 C, respectively. How long must the tube be made if the outlet temperature of the...
