Cold water enters a counter flow heat exchanger at 20ºC at a rate of 10 kg/s,...
Cold water enters a counter flow heat exchanger at 20ºC at a rate of 10 kg/s, where it is heated by a hot water stream that enters the heat exchanger at 80ºC at a rate of 2 kg/s. Assuming the specific heat of water to remain constant at Cp=4.18 kJ/(kg.ºC), determine the maximum heat transfer rate and the outlet temperatures of the cold and the hot water streams.

Hot water enters a counter-flow double-pipe heat exchanger at 180F with a velocity of 5 ft/s. Cold water at 80F flows at 3 ft/s in the outer section of the exchanger. The diameter of the inner pipe is 1 inch, the pipe wall thickness is 1/8", and the outer pipe diameter is 2 inches. The overall heat transfer coefficient times area per unit length UA/L = 150 Btu/hr-ft-F. If the exchanger is 16 feet long, what is the exit temperature...

Problem #1 Saturated steam at 300°C is used to heat a counter-currently flowing stream of methanol vapor from 65°C to 260°C in an adiabatic heat exchanger. The flow rate of the methanol is 5500 standard liters per minute (at STP), and the steam condenses and leaves the heat exchanger as liquid water at 90°C. a) Draw a diagram of the process. b) Calculate the required flow rate of the entering steam in m3/min. c) Calculate the rate of heat transfer...

A counter current double pipe heat exchanger is used to boil but not superheat water at 100 DegreeC at rate of about 0.1 kg/s. This is achieved by flowing hot oil at 400 DegreeC through the inner pipe at a rate of 5 kg/s. Latent heat of water: 2265 kJ/kg Heat capacity of water: 4180 J/kgK Heat capacity of the oil: 1800 J/kgK What is the temperature of he hot oil leaving the heat exchanger? What is the overall heat...

Oil enters a counterflow heat exchanger at 600 K with a mass flow rate of 10 kg/s and exits at 350 K. A separate stream of liquid water enters at 20°C, 5 bar. Each stream experiences no significant change in pressure. Stray heat transfer with the surroundings of the heat exchanger and kinetic and potential energy effects can be ignored. The specific heat of the oil is constant, c = 2 kJ/kg · K. If the designer wants to ensure...

A heat recovery unit in a factory uses a shell-in-tube counter flow type unit to recover heat from a flow of hot fluid to preheat water for the factory. The hot fluid enters at 88°C and a flow rate of 25 kg/minute, and exits at 55°C. The cold water will enter the heat exchanger at 15°C and exit at 55°C. Take cHot-fluid = 3000 J/kg.K, cwater = 4200 J/kg.K. PART (b) An air to water heat exchanger with an effectiveness...
