bekas [8.4K]

Answer:

x = 10

If the pressure in the tank is 1.5 bar and atmospheric pressure is 1 bar, determine l, in m, for water with a density of 997

il63 [147K]

this can be solve using the formulaP = rghwhere P is the total pressurer is the densityh is the heightg is the acceleration due to gravity
fist solve the total pressureP = 1.5 bar + 1 barP = 2.5 barP = 250,000 Pa
P = rgh250,000 = (997)(9.81)hh =25.56 m
