A chemical process stream enters a shell-and-tube exchanger at a temperature of 200.0°Fand does two passes on the shell side, exiting the exchange at 170.0°F. The Heat exchanger Spring 2021 has 200 stainless steel tubes that are 2-in. ODand 10.0ft long. Indicate whether the temperature of the process stream will increase, decrease, or remain the sameunder the following scenarios. You must justify your answerto receive full credit. a)The flow rate of the cooling fluid is increased. b)There are 200 tubes that are 1.0-in. OD and 20.0ft long. c)The number of shell passes is doubled. d)The tube material is changed to copper.
