A pump delivering water at a temperature of 400 F (204.4 C) and a rate of 12,000 GPM (757 lit/s) to a pressurized vessel at 1000 psia. The discharge piping is 135 ft (41.15 m) long schedule 40 stainless steel, and nominal pipe size of 20 in  (7.874 cm). Find the total dynamic discharge head

Water at 25°C is pumped at 1800 gal/min from the lower to upper reservoir, as shown in Figure below (Zı = 30 ft and z2 = 180 ft). Pipe friction losses are approximated by hf = 35V/2g, where V is the average velocity in the pipe. The pump is 80% efficient. (a) Find the head loss due to friction, hẹ in ft. in horse power (b) Compute the pump head, h, in ft and the pump power needed, Ppump (hp). Given: Specific weight of water, ywater = 62.4 lb/ft'; 1 ft/s = 448.8 gal/min. Show all calculations. Z2 = 180 ft Z¡ = 30 ft D= 6 in Pump
