Good morning i have this problem but i am confused in the part that states the vapor space is 1psi. do you think you could help me with it?

  1. A sealed tank has a liquid with a specific gravity of 1.00 in it. The pressure in its vapor space is 1 psi. If the height of the liquid is 10.0 ft, how much head pressure, in inches w.c., will it exert?

Answer #1

Given Data Specific Gravity of liquid, SG 1 Pressure in the vapor space, p 1 psi Weight density of water, w 62.4 lbf /ft Height of liquid, h-10ft Write the weight density of given liquid. Here, the weight density of given liquid is y Substitute the given values in the above expression 7 62.4x1 - 62.4 1bf /ft Write the expression for the pressure due to liquid height Substitute the given values in the above expressionP 62.4x 10 = (624 lbf/ft2/000694444 psi 11bf /ft 4.33 psi Calculate the net pressure in the tank. Pet P+p Substitute the given values in the above expression. et 4.33 psi +1psi 5.33 psi Calculate the net head Here, the head is H Substitute the given values in the above expression. 5.33 psi ( 62.4 lbf/ft3 )1-1ft 1728 in -147.6 in Thus, the head is 147.6in
