Including the suction pump head including swimming pool filtration systems, approximately pump outlet and inlet pressure difference. Lift with H expressed in meters (m). Pump pressure P expressed by units of Mpa (MPa), H = P / ρ. As P of 1kg / cm2, then H = (lkg / cm2) / (1000kg / m3) H = (1kg / cm2) / (1000 kg / m3) = (10000 公斤 / m2) / 1000 公斤 / m3 = 10m 1Mpa = 10kg / c m2, H = (P2-P1) / ρ (P2 = outlet pressure P1 = inlet pressure) Guangzhou City-Cape QLDK body equipment installed Ltd. focuses pool / swimming pool equipment, swimming pool design swimming pool filter pumps, sauna and swimming pool design and installation, engineering design and construction of swimming pools, landscape water treatment equipment, swimming pool circulating water filtration equipment and other services.
