A double-pipe heat exchanger with a partial bypass for the cold stream is shown in Figure. The mass flow rate of the hot stream wh, and the bypass fraction, f, can be manipulated. Heat losses can be neglected.(a) Determine the model degrees of freedom, NF, arid the control degrees of freedom, NFC, based on a steady-state analysis.(b) Determine the number of disturbance variables, N, and specify reasonable choices for the disturbance variables.(c) Would NF or NFC change if a cocurrent heat exchanger configuration was analyzed instead of the countercurrent configuration?
