Q4- The image below shows the plan view of a round metal ductwork supplying air from a fan coil unit to 4 air terminals. The flowrate for each section is shown in the image. Assuming a friction rate of 0.1inch water/100 ft ductwork, determine the duct size for each section. Hint: for ducting the size you can use https://www.oceanhvac.com/ductulator/ website (in the case you are using this website, consider a TEL of 100 ft), or any other online ductulator website or software. You just need to enter the friction rate and the CFM to find the appropriate round duct size. 800 cfm 600 cfm 400 cfm 200 cfm 200 cfm 200 cfm 200 cfm
