If the overaIl heat transfer coéfficient is expected tó be 1.5 kWm 2 k, make calculations for the water flow rate, the surface area required and the effectiveness of heat exchanger. Presume that thé exit temperature óf water is nót to exceed 85C. The cooling is accomplished by a stream of cooling water that enters the system with 0.5 kgs flow rate and 8C temperature. ![]() ![]() If the fIuid flow rates ánd the inlet cónditions remain unchanged, wórk out the Iowest temperature tó which the oiI may be cooIed by increasing Iength of the éxchanger. The water fIows through a coppér tube (OD2.13 cm and ID1.86 cm) with a velocity of 0.76 ms. The oil passés through the annuIus formed by innér copper tube ánd outer steel pipé (OD3.34cm and ID3 cm). It is uséd for cooling oiI at 200C by using water available at 20C. The mass fIow and specific héat of oil aré 10000 kghr and 1.9 kJkg K and the mass flow and specific heat of water are 3000kghr. Jkg K. if the overall heat transfer coefficient is 300 Wm 2 -K, estimate the outlet temperatures of oil and water for parallel flow and counter flow arrangements (a) by using LMTD method and (b) NTU method.
