Mechanical principles engineering question help??
A boiler is supplied with water at a rate of 0.5 kg/s through a pipe of diameter 80mm
a) Calculate the velocity of the water in the pipe
b) Calculate the smaller internal diameter of this tapered section of pipe calculate the velocity to be 2.5 times greater than the entry velocity calculated earlier.
Assume density is 1000kg/m^3
a) m= PVA
b) V1A1=V2A2
a) Mass flow rate = 0.5kg/s
Velocity=?
Area = 5.03 x 10^-3
Density = 1000kg/m^3
so m=P1V1A1
V=P1XA1/m
V= (1000)x(5.03x10^-3) / 0.5kg/s = 10.06m/s
Thanks for anyone who attempts to help me, i really appreciate it as this is my last assignment of the year:)
