Water is released from a water tank through a pipe to the
atmosphere. The pipe diameter is 8 mm
and the length is 6 m. Water temperature is 15 oC. The
resistance coefficient of the pipe f = 0.015
and the difference between the water surface and the pipe outlet is
3 m. Determine the exit velocity
of water and sketch the Hydraulic Grade Line (HGL) and Energy Grade
Line (EGL) along the pipe.

Water is to be heated from 10 °C to 83 °C as it flows through a 0.015 m-internal-diameter, 13-m-long tube. The tube is equipped with an electric resistance heater, which provides uniform heating throughout the surface of the tube. The outer surface of the heater is well insulated, so that in steady operation all the heat generated in the heater is transferred to the water in the tube. The system provides hot water at a rate of 5 L/min Assumelp...

Anaerobic water at 20 °C must be transported from one tank to an open container through a pipe with ID = 5.2 cm. Since N2 gas was used to make the water anaerobic, the plant decided to move the water by displacing it with N2 gas under pressure. The closed tank is connected to a gas tank that delivers a constant pressure of 40 psig at the tank gas phase. The exit pipe is 4.6 m above the tank exit...

Water (p=998kg/m^3,
u=0.001Pa*s) flows from reservoir A to reservoir B through the
piping system shown. Each elbow has a minor loss coefficient of
1.2. Each valve has a minor loss coefficient of 3.2. The entrance
and exit are both sharp edged. Determine the flow rate L/min. You
now need to modify the piping system to increase the flow rate to
100L/min by reducing the length of the 25mm pipe. What must new
length of the 25mm pipe be?

1. a) 1 m of water is flowing through a pipe in 10 minutes. The diameter of the pipe is 1.5 cm. Calculate the velocity of the water inside the pipe. 2. b) The pipe is extended to a bending and an elbow system. The head loss for bending and elbow system is 500 mm and 900 mm respectively. Calculate the loss coefficient for both the systems. Which one has higher loss coefficient and why?

8. (15 points) Water flows through a 2-in diameter pipe with a velocity of 15 ft/s as shown in the figure below. The relative roughness of the pipe is 0.0004 ft, and the loss coefficient for the exit is 1.0. Values for the liquid height in the tank (2) and the pipe length between the standpipe and tank (L) are 8 ft and 8 ft, respectively. Determine the height, h (ft), to which the water rises in the standpipe. P...
