A counter flow single body single pass heat exchanger is used to cool the lubricating oil of an industrial gas turbine. The flow rate of the cooling water flowing in the pipe is 0.2 kg/s and the pipe diameter is 25mm. The flow rate of the oil flowing between the pipe and the body is 0.1 kg/s and the body diameter is 45 mm. Oil enters at 100°C, while water enters at 30°C. What should be the length of the pipe so that the outlet temperature of the oil is 60 °C ?

! Required information Consider operation of a single-pass cross-flow heat exchanger with water (cp=4193 J/kg-K) (mixed) and methanol (cp=2577 J/kg-K) (unmixed). Water entering and exiting the heat exchanger at 93°C and 60°C, respectively, is used to heat the methanol initially at 10°C. The overall heat transfer coefficient and the total heat transfer rate is estimated to be 650 W/m².K and 250 kW, respectively. An effectiveness of at least 0.5 is to be achieved. Calculate the mass flow rate of water. (Round the answer to two decimal places.) The mass flow rate of water is kg/s.
Glycerin (cp=2400J/kgK) at 20oC and 0.5kg/s is heated by ethylene glycol (cp=2500J/kgK at 50oC at the same mass flow rate.

A 2 - shell pass & 4 - tube pass heat exchanger is designed to heat water from 40 C to 90 C flowing inside the tubes at a rate of 7.5 kg/sec while hot gases flowing in the shell at a rate of 10.42 kg/sec with temperature leaving the heat exchanger at 110 C. Consider the specific heat of water and gas of 4.2 kJ/kg K & 1.08 kJ/kg K, respectively. Draw the temp-profile showing the multi-pass effect and determine the temperature of gas entering the heat exchanger.
