The figure shows two air chambers A and B, where two manometers are being used to measure the air pressure. The manometric fluid is the same in both manometers, with a specific gravity of (S). The fluid heights in the two manometers are (ha) and (hb). Given the values of S [-], ha [mm], and hp [mm], calculate the gage pressure in chamber A in [Pa]. Chamber A Pgage = ? Chamber B Tha hp
