Question
these terms has the dimensions of energy per mass of fluid by a. converting each term to units of Btu/lbm, beginning with pressure in psi, density in Ibf3, velocity in ft/s, and height in ft b. converting each term to units of J/kg, beginning with pressure in Pa, density in kg/m3, velocity in m/s, and height in m 5. One way to drain a liquid out of a container that has high walls is to use a siphon: a tube is placed with one end in the liquid and the other end over the wall of the container as shown on the next page. The tube is then filled with the liquid (usually by applying suction to the open end). As long as the elevation of the open end is lower than that of the top of the liquid, the liquid will flow out of the tank. (continued on the next page)Explanation / Answer
Applying Bernouli Equation between h=0 and h=h
P1/p+ V12/2 +gZ1= P2/p+ V22/2 + gZ2
P1=P2 and V1<<V2
Z1-Z2= h
V2 =Sqrt(2gh)
h= o Velocity, V2 =0
for h= 7cm =7/100m
V2= 1.17 m/sec
Volumetic flow rate =V2*Cross sectional area = 1.17*(3.142/4)*(1/100)2=9.2*10-5 m3/sec
