During the retrofit of a chemical plant, it was decided to place valves and bypass lines around two exchangers placed in series. The flows through each of the bypass lines are controlled by the valves so that \(40 \%\) of the flow bypasses each exchanger. Because of safety concerns, the bypass lines must be removed. These situations are illustrated in Figure P22.16(a), and the pump curve is in Figure P22.16(b). From the information given in the following table, find the following:

a. For the base case, what is the flowrate through the pump?

b. For the new case, what the maximum flow that can be sent through the two exchangers?
