(a)
An oil pipeline and a rigid air tank are connected to each other by a manometer, as
shown in Figure 1. The h, is 75 cm and he is 20 cm. The standard density of water is
1000 kg/m³ while the gas constant of air is 0.287 kPa.m³/kg.K. If the atmospheric
pressure is assumed to be 100 kPa, determine the gage pressure at A, in kPa.
