Water enters a 2 meter diameter pipe at a temperature of 23 deg C. The water leaves the pipe at a temperature of 97 deg C The laminar flow rate is such that the Reynolds number is 800. What is the mass flow rate?
a) Less than or equal to 0.5 kg/sec.
b) Equal to or greater than 0.2 m/sec.
c) Greater than 0.5 kg/sec.
d) Cannot be determined from the information provided
Use average temperature = (97+23)/2 = 60 C.
Density = 983 kg/m3
The mass flow rate for a laminar flow with a Reynolds number of 800 is determined. The pipe at different temperatures is analyzed.
