()/(m^(2))is flowing through a pipe as shown in the figure. The pipe has diameters
D_(1)=10cmand
D_(2)=5cm. Both pipes are smooth. The lengths are
L_(1)=1mand
L_(2)=1m. The flow rate is
0.05(m^(3))/(s). Answer the following questions (Assume gravitational acceleration
g=9.81(m)/(s^(2))): (a) Using a manometer to measure the pressure difference between the inlet and outlet of the valve, the height difference
h=1.68cmis obtained. The manometer is filled with a liquid of density
200k(g)/(m^(3)). What is the valve's loss coefficient? (b) Determine the minor loss in meters from the pipe inlet to the outlet. (c) Determine the major loss in meters from the pipe inlet to the outlet. (d) Calculate the power required to move the air through the pipe.
