Question

A fluid with an average speed of 2.1 m/s flows through commercial steel tubing with a diameter of 2 mm and a length of 200 m. The tubing contains 10 regular threaded elbows and the discharge end of the tube is 60 m lower than the inlet. Calculate the pressure drop inlet to exit assuming the fluid is: a) air with average properties of 100 C, 200 kPa. b) water at a temperature of 20 C
