Q2l Calculate size of each part for the air conditioning ducts system shown in Figure(1) by using equilibrium pressure drop method. The velocity of air in main duct 7 m/s. Tabulate the results (velocity value, rate of pressure drop, circular diameter, and air flow rate) for each part, then convert circular ducts to equivalent rectangle ducts at height 300 mm for all system. 0.5 m³/s E 5m A D 0.5m³/s 3m B Figure (1) 3m 3m 5m C 1 m³/s
The pressure of a reactor vessel can be adjusted bychanging either the inlet or outlet gaseous flow rate. Theoutlet flow is kept fixed as long as the tank pressure remainsbetween 100 and 120 psi, and pressure changes are treatedby manipulating the inlet flow control valve. However, if thepressure goes higher than these limits, the exit gas flow isthen changed. Finally, if the pressure exceeds 200 psi, a ventvalve on the vessel is opened and transfers the gas to a storagevessel. Design a control scheme that meets the performanceobjectives. Draw a process instrumentation diagram for theresulting control system
The minimum fresh air requirement of a residential building is specified to be 0.35 air change per hour (per ASHRAE standards). That is, 35% of the entire quantity of air contained in a residence should be replaced by fresh outdoor air every hour. The ventilation requirement of a 3-meter highresidence with 150 square meters of floor space is to be met by air provided by a single fan.a. Determine the required flow capacity of the fan (in m3/min).b. Find the diameter of the fan duct required (circular cross-section) if the average air velocity from the duct is to be 3 m/sec.
During breathing, the flow rate of air into and out of the lungs is 12 L/min. The trachea through which air flows is 1.8 cm in diameter. Approximate the Reynold's number for airflow in the trachea during inhalation.
A circular pipe of I.D. 4 m is bifurcated into two pipes of I.D. 2 m each. If the average velocity of water flowing through the main pipe is 5 m/s, then the average velocity through the bifurcated pipe is
As an engineer, you are setting up an experiment to measure the airflow rate in a duct. Choose a technique and devices for the measurement. You are required to design/draw the set-up and demonstrate the calculation for themeasurement of flow rate. Please discuss the relevant principle involved and reason for selectingthe technique.
Water travels through a circular pipe with a diameter of 400 mm and at a speed of 5 m/s. The inertial force created by the flow is: Question 2Answer a. 100000 kgs/m b. 10000 kgs/m c. 1000 kgs/m d. 1000000 kgs/m
Pum 2 cm I.D. Ball Valve Patm Problem 2: The drain on a large tank of liquid consists of a ball valve with a 2 cm inside diameter that connects to the tank with a well-rounded flow entrance. The height of the fluid surface above the valve entrance is denoted h. The pressure in the air space above the surface of the fluid is the same as that outside of the tank, Patm. Taking the losses to come solely from the ball valve and its entrance region, perform the following analysis: a. Find the velocity of the flow through the valve and the flow rate (in liters/sec) when h = 6 meters and the valve is fully open. b. Find the increase in fluid height h required to maintain the same flow rate as that found in Part a. with the ball valve 1/3 closed. c. How does the change in fluid height in Part b. compare with the increase in head loss caused by the partial closing of the valve?
