Q1: Water flows in a circular pipe. At one section the diameter is 0.3 m the static pressure is 260 kpa gauge, the velocity is 3 m/s and the elevation is 10 m above ground level. The elevation at a section downstream is 0 m and the pipe diameter is 0.15 m. Find the gauge pressure at the downstream section. Frictional effect may be neglected. Assume density of water to be 999 kg/m³. *****************
This is thermodynamics subject. I need complete solution (step by step process) with given. Thanks Note: Instead of using g = 9.81 m/s^2, use the g = 9.806 m/s^2.
A fan described in a manufacturer's table is rated to deliver 500 m 3/min at a static pressure (gage) of 254 cm of when running at 250 rpm dad requiring 3.6 kW. if the fan speed is changed to 305 rpm and air handled was at 65c instead of standard 21c, find the power in kW.
Q2: Water flows through a pipe AB 1.2 m diameter at 3 m/s and then passes through a pipe BC 1.5 m diameter. At C, the pipe branch. Branch CD is 0.8 m in diameter and carries one- third of flow in AB. The flow velocity in branchi CE is 2.5 ms. Find the mass rate of flow in AB, the velocity in BC, the velocity in CD and the Reynolds number of CE 1.2 m 1.5m Me Or Q: VCE-25

Example (6-1): At the best efficiency point a centrifugal pump, with impeller diameter D=8 in, produces H= 21.9 ft at Q=300 gpm with N=1170 rpm. Compute the corresponding specific speed using a) U.S. customary units. B) SI units (rad/sec, m/sec, m'/sec").c) European units (rev/sec, m/sec, m/sec?). Develop conversion factors to relate the specific speeds.
