-S) APR 29 QUESTION 2 (40 pts) Name: ID#: a.(10pts) The diameter of a cast-iron pipe is 15 inches and the Reynold number for the flow of water through the pipe is estimated as 5.0 x 105. What is the friction factor for this condition? (Relative roughness & is 0.26 mm) b.(12pts) Water at 25C flows at a rate of 0.04 m/s in a 30 cm diameter pipe. Would you expect the flow to be laminar or turbulent? (Dynamic viscosity of water is 8.9 x104 Pa.s, densitry of water is 997 kg/m) c.(18pts) Glycerin oil at 25C is flowing steadily in a 50 m long and 4 cm diameter horizontal pipe made of stainless steel at a rate of 2x10-2 m/second. Determine the following: (Glycerin oil density is 1261.3 kg/m, dynamic viscosity is 0.95 Pa.s.) , Calculate the pressure drop Calculate the head loss Focus P
