Question

please provide explanation and answers. thanks!

The 10-cm orifice in the horizontal 30-cm pipe shown is the same size as the orifice in the vertical pipe. The manometers are mercury-water manometers, and water (T = 20 degree C) is flowing in the system. The gages are Bourdon-tube gages. The flow, at a rate of 0.1 m3/s, is to the right in the horizontal pipe and therefore downward in the vertical pipe. Is delta p as indicated by gages A and B the same as delta p as indicated by gages D and E? Determine their values. Is the deflection on manometer C the same as the deflection on manometer F? Determine the deflections. PROBLEM 13.29

Explanation / Answer

no delta p will not be the same in D nad E as that of A and B as the flow rate will be different in vertical pipe due to potential difference developed due to height.

no deflection will not be same C and manometer F due to difference in heights

Presssure of A= Pressure of B

Pressure of D-Pressure of E = 1000*9.8*.3 =2940 pa
