4. Water at 100 psig is flowing inside a 2 in sch 40 pipe (D₁ = 0.1723 ft) at a rate of 25 lb/s, then it flows through an additional pipe of 1 in sch 40 (D2 = 0.0874 ft) and leaves this second pipe at 40 psig at an elevation 20 feet above the inlet to the large pipe. No pump is used in the set- up. The net heat imparted from the surrounding is 1500 BTU/hr. Calculate the total friction expressed in lbf-ft/lb.
