A parallel flow double pipe heat exchanger is constructed using a ¾-nom sch 5S stainless steel outer pipe and a ½-std type M copper tube. Ethanol enters the tube at 900 lbm/h and a temperature of 80°F. Water flows through the annulus at 1,200 lbm/h and it enters the heat exchanger at 140°F. The heat exchanger is 6-ft long with no hairpins. For a clean heat exchanger, determine the

a. Outlet temperatures of the hot and cold fluid flows

b. Heat transfer rate (Btu/h) between the hot and cold fluids

c. Pressure drop through the inner tube (psi)

d. Pressure drop through the annulus (psi)
