Question 4 Correct Mark 4.00 out of 4.00 Question 5 Correct Mark 4.00 out of 4.00 70678494: A05Q04 5.32 Vapour refrigerant volume flow rate Category: Assignment 05 70678499: A05Q05 5.35 Furnace air flow rate Category: Assignment 05 After a liquid refrigerant is flashed into a vapor its specific weight is 10.9 N/m . If the weight flow is 29.3 N/h, compute the volume flow rate in m /s . (round the final answer to three significant figures ) Answer: 7.47E-4 m 3 3 γ fluid = w fluid V fluid w fluid = γ fluid × V fluid Q fluid = V fluid t W fluid = w fluid t Therefore W fluid = γ fluid × Q fluid Q fluid = W fluid γ fluid Q Refri = W Refri γ Refri = 29.3 N h 1 h 3600 s 10.9 N m 3 = 0.0007466870540265 m 3 s The correct answer is: 7.47e-4 m3/s ( ) A furnace requires 1223 lb/h of air for efficient combustion. If the air has a specific weight of 0.062 lb/ft , compute the required volume flow rate in ft /s . (round the final answer to three significant figures ) Answer: 5.48 ft3/s 3 3 The correct answer is: 5.48 ft3/s
Question 6 Correct Mark 4.00 out of 4.00 Question 7 Correct Mark 4.00 out of 4.00 70678496: A05Q06 5.37 Pipe diameter Category: Assignment 05 70678487: A05Q07A 5.39 Average velocity in reduction Category: Assignment 05 Calculate the diameter of a pipe that would carry 61.2 ft /s of a liquid at an average velocity of 5.1 ft/s. (round the final answer to three significant figures ) Answer: 3.91 ft 3 The correct answer is: 3.91 ft When 2333 L/min of water flows through a circular section with an inside diameter of 300 mm that later reduces to a 191-mm diameter, calculate the average velocity of flow in the first section . (round the final answer to three significant figures ) Answer: 0.550 m/s The correct answer is: 0.550 m/s
Question 8 Correct Mark 4.00 out of 4.00 70678501: A05Q08 5.41 Velocity in tee branches Category: Assignment 05 Answer: 6.49 m/s The correct answer is: 6.49 m/s ◄ Assignment 5, Chapter 5 (Buoyancy) Jump to... Assignment 6, Chapter 6 (Flow of Fluids & Bernoulli's Energy Equation)
