6. (25 points) Water at standard atmospheric conditions flows through a 100 m long plastic pipe with a circular cross section of diameter D = 0.2 m at an average velocity of 10 cm/s. The flow exits into the atmosphere. The pipe material is smooth and has essentially no roughness. What is the pressure at the pipe entrance if it is horizontal? What is the pressure at the pipe entrance if the elevation increases by 50 cm? A Moody diagram...

10 peles A 3-m-diameter tank is initially filled with water 2 m above the center of a sharp-edged 10 cm diameter orifice. The tank water surface is open to the other, and the orice drains to the atmosphere through a 100-m-long pipe. The initial discharge velocity is 4 m/s. The friction coefficient of the can be when to be 0.015 and the effect of the energy correction the factor can be neglected. Determine (a) the initial velocity from the tank...

Erample 12.7. Water is being pumped at the rate of 20 l/s to an overhead tank through a 15 cm diameter 300 m long delivery pipe. In the tank pipe discharges freely at height of 15 m above the pump. If head loss h = 0.03 for pipe, determine the pressure developed by the pump on its delivery side and power required to lift the water. Assume first 285 m of pipe is horizontal and rest is vertical.

Water at 20° flows in pipeline system shown below (Fig. 1) at rate of 32400 Vhr. Pipe 1 is 15m long and 0.044 m outer diameter and pipe 2 is 100m long and 0.034m outer diameter. The thickness of both pipes is 2mm. Pipe I is a ductile iron uncoated pipe and pipe 2 is ductile iron coated pipe. There are totally 4 elbows in the system (two elbows in each pipe) and the elbows are 90° street elbows. All...

(b) Water flows under gravity through a pipeline connecting two reservoirs as shown in Figure 2. The pipeline consists of 2 km of pipe diameter 400 mm and sand roughness equivalent 0.03 mm followed by an abrupt change to 3 km of 500 mm diameter pipe of sand roughness equivalent 0.08 mm. The pipe discharges as a free jet into a reservoir. The difference in elevation between the water surface of the upstream reservoir and the discharging jet is 21...

Water is to be pumped from one large, open tank to a second large open tank as shown in Figure 1. The pipe diameter throughout is 15 cm and the total length of the pipe between the pipe entrance and exit is 60 m. Minor loss coefficient for the entrance, exit and the elbow are shown, and the Darcy friction factor for the pipe can be assumed constant and equal...

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...
