Consider sterilization of the pharmaceutical product of Problem 8.27. To avoid any possibility of heating the product to an unacceptably high temperature, atmospheric steam is condensed on the exterior of the tube instead of using the resistance heater, providing a uniform surface temperature,
(a) For the conditions of Problem 8.27, determine the required length of straight tube,
(b) Consider replacing the straight tube with a coiled tube characterized by a coil diameter
(c) Calculate the pressure drop through the straight tube and through the coiled tube.
(d) Calculate the steam condensation rate.

- QUESTION 3 A multi-stage steam turbine exhausts into a two-pass surface condenser operating at a pressure of 10kPa. The steam enters the condenser with a dryness fraction of 0.85 and the condensate leaves the condenser at a temperature of 34.6°C. The tubes have an inside diameter of 18mm and a wall thickness of 1mm. Coolina water circulates through the tubes at a speed of 1.2m/s. The stean flows through the condenser at a rate of 2400kg/hr and air leaks into the system at a rate of 0.5kg/1000kg of steam condensed.

Ice water is flowing rapidly through inside tube and the inside wall temperature is 274.9K. The outside surface temperature is 297.1K. A total of 14.65W must be removed from the bath by cooling coil. How many m of tubing are required?arrow_forwardA shell-and-tube heat exchanger is used to cool compressed liquid methanol from 176 °F to 104 °F. The methanol flows on the shell side of the exchanger. The coolant is water that rises in temperature from 50 °F to 86 °F and flows within the tubes at a rate of 68.9 kg s1. Finding the appropriate thermophysical data and applying the proper equations, you are required to do the following: (a) Calculate i) methanol mass flow rate in the exchanger, ii) methanol volumetric flowrate at the inlet of the exchanger. (b) i) For the counter-current flow of the fluids calculate the log temperature difference, ii) explain the purpose of calculating this difference, iii) explain, quantitatively, why is the counter-current flow in heat exchangers preferred to co-current flow. meanarrow_forward
