Suppose that the turbine inlet and outlet pipes both have diameters of 0.5 meters. Shaw that It is, reasonable to neglect the change in kinetic energy for this unit. Given the following hot and cold process streams: Apply pinch analysis with a delta r_min = 10 degree C to answer the following questions: a) Draw and fully label the interval diagram. Determine the pinch point, clearly showing all the steps. What are the pinch point temperatures? What are the minimum heating and cooling loads? If you had used a different and larger value for delta t_min how you expect these to have differed? If you were asked to choose a value at value of delta T_min, what factors would you consider? Mention two and explain why. Design one integrated exchanger below the pinch, Identifying the amount of heat exchanged and the in/et and outlet temperatures of the streams involved.

Solution

design a two stage compound reverted gearbox to be used in a small power drill. To meet the requirement of low-torque and high torque setting, design the gearbox for two velocity ratios 8 and 40. the gear box is connected to a 2500 rpm. 10 hp electric motor and must be designed to work at an elavated temprature 400 F. The gears are to be made of 4140 Nitrided Steel
