Water (=62.4ft3lbm;v=1.66105sft2) flows through the coils of the horizontal heat exchanger shown below at a rate of 0.9 gal/min. The heat exchanger is composed of 0.5 in diameter copper pipe drawn tubing ( =5106ft ). There are seven 180 return bends (KL=1.5); ignore the length of the 180 return bends in your calculations. (A) Determine the Reynold's number for the flow of water through the pipe. (B) Using the Moody chart, determine the friction factor. (C) Determine the pressure drop between the inlet and outlet of the heat exchanger. ( P=0.325psi)
