Explanation:
Given that,
Diameter =100 mm
Volume = 100 liter
Time = 45 min
Viscosity = 0.005 Pas
Density = 900 kg/m³
(a). We need to calculate the volume flow rate of oil
Using formula of flow rate
Put the value into the formula
The volume flow rate of oil is
(b). We need to calculate the mean velocity in the pipe
Using formula of mean velocity
Put the value into the formula
The mean velocity in the pipe is .
(c). We need to calculate the Reynolds number
Using formula of the Reynolds number
Put the value in to the formula
The Reynolds number is 84.6.
(d). We need to calculate the maximum velocity in the pipe
Using formula of maximum velocity
Put the value into the formula
The maximum velocity in the pipe is
Hence, This is the required solution
