Question: In a chemical process plant, liquid isobutane at 50°F is being transported through a 30-ft-long standard 3/4-in Schedule 40 cast iron pipe with a mass flow rate of 0.4 lbm/s. Accuracy of the results is an important issue in this problem; therefore, use the most appropriate equation to determine
(a) the pressure loss and
(b) the pumping power required to overcome the pressure loss. Assume flow is fully developed. Is this a good assumption?
