(a) if the pressure in the tank is 1.5 bar and atmospheric pressure is 1 bar, determine L, in m, for water with density of 997 kg/m^3 as the manometer liquid.
Let g = 9.81 m/s^2.
(b) determine L , in cm, if the manometer liquiud is mercury with a density of 13.59 g/cm^3 and the gas pressure is 1.3 bar. A barometer indicates the local atmospheric pressure is 750 mmHg. Let g = 9.81 m/s^2.
