Fluid X56-1 (density = 1300 kg/m3; M = 253 kg/kmol) is pumped at a rate of 4.58 m3/hour from a storage tank to a processing unit. The pressure at the inlet to the processing unit is atmospheric while the air pressure in the storage tank is 1.25 atm. The storage tank contains fluid with a height of 1.8 m. The pump, located just outside the bottom of the tank, has a pressure at the exit point of 350 kPa. The pump is located 15 m lower than the processing unit. The pipe transporting the fluid is commercial steel with an inside diameter of 3 cm. Assume the viscosity is 42 mPa*s. a) What is the Reynold’s number for flow in the pipe? b) Is the flow laminar or turbulent? c) What is the pressure (kPa) at the inlet of the pump
