Water is being ejected at the rate 0.2 mil min from a live hydrant with a diameter of 0.15m at the inlet (flange). The diameter redures to 0.02 m at the outlet. The inlet pressure is 200 kPa (absolute) and the exit pressure is atmospheric. Neglect the weight of the pipe and fluid and assume a steady-state flow. Determine (a) inlet and outlet velocities and (b) the torque acting on the flange. Assume g=9.8 mish, Pwater = 980 kg/m², Patm...

A centrifugal pump is pumping water at a rate of 35.55 gal/min. The pressures at the inlet, and outlet of the pumps are -2.26 psig and 7.715 psig respectively. The outlet pipe is placed 10 inches higher than the inlet pipe. The inlet and outlet diameters of the pipe are 1.85 in and 1.6 in respectively and the torque produced by the pump rotating at 1593 rpm is 3.172 ft.Ibf. Calculate the following in SI units: a) Total head b)...

Water flow in a pipe and then exit through a bended nozzle as shown in Figure 3. The nozzle is connected to the main pipe using a flanged joint at (1). The diameter of the pipe is D1 10 cm and is constant, whilst the diameter at the outlet section of the nozzle (2) is D2 3 em. The flowrate of the water is Q = 15 liter/s and the water pressure at the flange is Pi 230 kPa. By...

Two water reservoirs A and B are connected to each other through a 35m-long, 2-cm-diameter cast iron pipe with a sharp-edged entrance. The pipe also involves a swing check valve and a fully open gate valve. The water level in both reservoirs is the same, but reservoir A is pressurized by compressed air while reservoir B is open to the atmosphere at 94 kPa. If the initial flow rate through the pipe is 1.2 L/s, determine the air pressure (gage)...

Problem 1. Water flows from a large tank through a smooth pipe of length 80 m. Both the tank free surface and jet exit are exposed to the atmosphere. Take the density of water p = 1000 kg/m3, dynamic viscosity of water u = 0.001 kg/m.s, atmospheric pressure = 100 kPa, and gravity = 9.8 m/s2. Calculate the volumetric flow rate through the pipe. Neglect entrance losses to the pipe. Hint: Consider the inlet and outlet sections of the pipe...

Water flows at speed of 6 m/s through a horizontal pipe of
diameter 3.5 cm. The gauge pressure P1 of the water in the pipe is
1.7 atm. A short segment of the pipe is constricted to a smaller
diameter of 2.4 cm .
What is the gauge pressure of the water flowing through the
constricted segment? Atmospheric pressure is 1.013 × 10^5 Pa. The
density of water is 1000 kg/m^3 . The viscosity of water is
negligible. Answer in...
