A 2-in. diameter orifice plate is inserted in a 3-in. diameter pipe. If the water flow rate through the pipe is 0.90 cfs. (take your density equal to 1.94 slugs/ft3, and absolute viscosity equal to 2.34 x 10-5 lb. s/ft2). What is the velocity of the air (in ft/s) passing through the device before the orifice plate? (Give your answer in two decimals, do not enter any units)
