Answer to Question #223932 in Mechanical Engineering for Unknown346307

Question

The fig figure below shows water flowing through a pipe reducer. the static pressure at(1) and (2) are measured using the manometer with a fluid of SG < 1 find( by applying Bernoulli's equations) a) barometer reading X=f (Q,A1,A2,SG)

b)p1-p2=f(theta,r,SG,L)

c)if the vapour pressure of the water at the prevailing conditions is p=1.765kPa ,what the minimum area ratio(A2/A1) to prevent cavitation.

Assume P1/P2=5.6,SG=0.85,Q=0.05m3/s,D1=0.3m,L=1.5m and theta=30°
