a) Action: For a specific fan hardware unit, the fan curve's functional relationship between AP (inches of water) and cfm is as follows AP=4 -0.2 [( c?m 2 1000 c?m 1000 1 while the system curve is c?m 2 AP = 0.8 ( 1000) After equating the above fan and system curves, determine the value of AP in inches of water and cfm at the operating point. Show work and/or explain exactly how you arrived at the solution (ans: 3.54 inches and 2102 cfm)
