Answer:
Reynolds number is 293068.43.
Explanation:
Step1
Given:
Water temperature is 98 °F.
Diameter of the pipe is 4 in
Length of the pipe is 870 feet.
Flow rate of water is 260 gallons per minute.
Calculation:
Step2
Water kinematic viscosity at temperature 98 F is ft²/s.
Find the velocity of the water as follows:
Q=AV
V=6.638 ft/s
Step3
Expression for Reynolds number is given as follows:
Here, v is velocity, is kinematic viscosity, d is diameter and Re is Reynolds number.
Substitute the values in the above equation as follows:
Re= 293068.43
Thus, the Reynolds number is 293068.43.
