Hydrogen is flowing through 500 feet of 6-in schedule 40 glass tubing at a rate of 1000 ft/min. Determine the pressure drop in psi 1 2. Two closed tanks 500 feet apart contain an oil (SG=0.85,100 CP) and are connected by a 3-in schedule 40 wrought iron pipe. The level in tank A is 20 feet above the level in tank B, and the gas pressure in the tank Bis 10 psi higher than in tank A. a. What is the flow rate of oil flowing through the pipe in ft/min? b. Which way is the oil flowing? 3. For an allowable pressure drop of 1 Pa/m, determine the minimum pipe size to move air at a rate of 100 m/h in a commercial steel: Circular duct (provide diameter, D. in cm) b. Square duct (provide side length, I. in cm)
