Cylindrical tank 4.4 m in diameter and 14.2 m high contains 7.7 m of fluid (SG = 0.67) and 6.5 m of another fluid with SG of 1. An orifice 100-mm diameter is located at the bottom with Cc = 0.66 and Cv -0.92. Compute the time to drain all the liquids. Group of answer choices 5640.61 sec 5720.61 sec 5680.16 sec 5600.16 sec A fluid with SG of 1 is being pumped at a rate of 0.275 m3/s, and it is assumed that the head loss from the reservoir to the gage is 3 times the velocity head in the 25 cm diameter pipe. Compute for the efficiency of the pump assuming that it can deliver 110 hp. Let z1 = 12m, diameter for inlet pipe = 50 cm, z2 = 18m, diameter for outlet pipe = 25 cm, Pressure at pt.2 (or gage) = 110 kPa. Group of answer choices 96.7 % 77.6% 87.6% 66.7 % A fluid with SG of 1 is flowing at a rate of 0.275 m3/s, and it is assumed that the head loss from the reservoir to the gage is 3 times the velocity head in the 25 cm diameter pipe. What power must the pump supply (in hp)? Let z1 = 12m, diameter for inlet pipe = 50 cm, z2 = 18m, diameter for outlet pipe = 25 cm, Pressure at pt.2 (or gage) = 110 kPa.
