Zadacha 1a

Task 1a. The pump pumps liquid with a density of, kg/m3. The pressure gauge reading on the discharge pipeline is 1.8 kgf/cm2 (0.18 MPa), the vacuum gauge reading (discharge) on the suction pipeline in front of the pump is 29 mm Hg.The pressure gauge is connected 0.5 m above the vacuum gauge. The diameters of the suction and discharge pipelines are the same. What pressure does the pump develop? a) p =800 kg / m3, b) p =850 kg/m3, c) p =900 kg/m3.
