Fluid 1 flows at a speed of 700 kg/h from theinner tube of a double-pipe heat exchangeroperating in parallel flow arrangement. Inheating this fluid from 25 oC to 80 oC, the fluidno. 2 with an initial temperature of 215 oC andflowing between two pipes is used. Since it isknown that the exit temperature of the fluid no.2 from the heat exchanger is 100 oC; Calculatethe mass flow rate and external heat transferarea of the fluid no. 2 required to meet theseconditions. (Additional data: The specific heatcapacity of fluid 1 is 0.58 kcal/kg oC, the specificheat capacity of fluid 2 is 0.61 kcal/kg oC, theoverall heat transfer coefficient for the outerarea is 420 W/(m2K).)

Problem 4. In order not to damage the resistance in the kettles, the difference between the temperature of the heater and the fluid should not exceed 25 °C. If the heat transfer area between the fluid and the heater is 78.5 cm² and the heat transfer coefficient is 400 W/m².K, find the maximum allowable power of the heater in order to boil water?
A stream of ammonia is cooled from 100oC to 20oC at a rate of 180 kg/hr in the tube side of a double-pipe counter-flow heat exchanger. Water enters the heat exchanger at 10oC at a rate of 250 kg/hr. The outside diameter of the inner tube is 3 cm and the length of the pipe is 7m. Using the log-mean temperature difference, calculate the overall heat transfer coefficient (U) for the heat exchanger. Determine the log-mean temperature difference. Determine the heat transfer coefficient for the heat exchanger. Cp for ammonia is 5234J/kgK and cp for water is 4180J/kgK.
Design a vapor compression cycle using ammonia as the refrigerant thatwill be used to maintain the temperature of a stream at -20°C. The condenser is air-cooled and the ambient temperature may be assumed to be 25°C. Assume a compressor efficiency of 80% and allow for 2°C of temperature difference between streams in the evaporator and condenser for practical heat transfer.
Steam enters a heat exchanger operating at steady state at 2 bar with a specific enthalpy of 1845 kJ/kg and exits at the same pressure as a saturated liquid. The steam mass flow rate is 1.6 kg/min. A separate stream of air with a mass flow rate of 68.5 kg/min enters at 37 °C and exits at 66.3 °C. The ideal gas model with c, = 1.005 kJ/kg.K can be assumed for air. Kinetic and potential energy effects are negligible.
Transport Phenomena Question
A shell-and-tube heat exchanger is to be constructed for the purpose of heating air in the tubes from 60°F to 160°F. This will be accomplished by the condensation of steam at 220°F (see Fig. 1). lbm/hr, with a mass velocity of 7000 lbm/hr-ft². tubes are steel, with a 2 in. inside diameter, calculate (a) the required number of tubes, (b) the effective heat transfer area, and (c) the length of each pipe. (d) the pressure drop in the tube, assuming that the air enters at atmospheric pressure. The air flows at the rate of 50,000 If the Also, find steam T. = 220°F = 160 F T Cout = 60°F T Cin air T. hout = 220°F
