velocity head of water QUESTION #49 What is the velocity head of water running through a...
Problem 4. Water flows through a large tank having a diameter of 8 ft. The velocity of the water relative to the tank is given as Vi 16-r f/s. Water then leaves through two pipes. A 3ft pipe whose velocity of the water relative to the radius of the pipe can be expressed as V2-2.25- ts and a third pipe. Draw the control volume for this system What must be the average velocity of the third pipe if the diameter...
Please answer question 3 and

Question 3: Water flows from a reservoir through a 16-inch
diameter pipe and then discharges at a 2-inch nozzle. If the
velocity in the pipe is 5 ft/sec, what is the velocity in the
nozzle, in ft/sec?
Question 4: A water deliver company is trying to decide which
size pipe to use. They need to deliver 500 GPM and keep their
velocity below the 15 ft/sec threshold. What minimum size pipe
should they use?...
10.20 Calculate the head loss for fresh water at 70°F flowing at 5 ft/s through a concrete pipe of diameter 2 ft and length 1200 ft. If no minor losses occur, what horsepower pump is required to move the fluid along 1200 ft of horizontal pipe?

PROBLEMS 1. What is the Reynold's number for water flowing in a 24-inch circular pipe at a velocity of 6.21 ft/s? Is the flow laminar or turbulent? 2. Water is flowing in a 2/2-inch pipe with a discharge of 0.150 cfs. Find the Reynold's number for this flow. Is the flow laminar or turbulent? 3. Water is flowing in a 4-inch pipe with a discharge of 4.0 × 10-3 cfs. Find the Reynolds number for this...
there is a velocity head flowing through a pipe with a calculated cross sectional area (6 inch schedule 460) If the pipe’s cross sectional area is doubled from calculated cross section to an unknown ft2 in, then calculate the velocity and velocity head. Note: acceleration due to gravity is 32 ft/s2
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...
A concentric tube, parallel heat exchanger is used to warm cold well water running on the inside pipe from 10°C to 25°C overa meter of pipe using steam running through the outside pipe that enters the system at 140°C and leaves at 100°C. The inside pipe is made of copper and has an inner diameter of 4 cm, with a wall thickness of 0.25 cm. The outside pipe is made of a very-well insulating material, has a diameter of 7...
8. (15 points) Water flows through a 3-in diameter pipe with a velocity of 25 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 (z) and the pipe length between the standpipe and tank (L) are 6 ft and 10 ft, respectively. Determine the height, h (ft), to which the water rises in the standpipe. P...
Water flows through a cast iron pipe at a velocity of 4.2 m/s. The pipe is 400 m long and has a diameter of 150 mm. The friction factor is 0.00593. Determine the Reynolds number and head loss due to friction.
