The tank is 6 m above the ground level; the pressure inside the tank is 1.4 Mpa. The length of the straight pipe connecting the tank to the pump is 9.37 m, with a pipe diameter of 80 mm. The pressure loss in the pipeline is 0.45 m. The mass flow rate is 2000 kg/h, and the density is 530 kg/m3. The main component is liquefied gas. Required: effective net positive suction head: handshake
Your data is insufficient; there is no information on the temperature of the medium, or the saturated vapor pressure (vaporization pressure) of the medium at that temperature cannot be obtained.
