Q4 length in m=406
A straight transfer pipe of length L = 10 m and D = 1 cm carries a liquid in highly turbulent flow at a pressure drop DPinit; this pipe must be altered to accommodate a new unit operation in a process, but must maintain the same flow. The old and new geometry are indicated in the sketch below. This adds length DL = 1 m, and adds 2 short-radius 90-degree bends; the diameter remains the same. What fractional increase in pressure drop from DPinit is required to maintain the same flow rate?
You were asked to design a water storage tank for your processing plant. The tank is cylindrical-shaped tank with diameter of 8.0 m. The water is to be supplied by a horizontal pipe (internal radius, ri = 6.00 cm), where water is under initial pressure of 2.00 atm., and flowrate of 2.0 m²/s. A vertical pipe (internal radius, rɔ = 1.00 cm) is to carry the water to a height of 9.40 m, where it is to pour out freely into the tank until the depth is 2.00 m. Assume water density of 1000 kg/m³, and g = 9.81m²/s. i) Calculate the volumetric flowrate and pressure at the pipe outflow.
