Given: An array of 14x14 tubes has steam condensing in it so that the tube surface temperatures are 100ºC. Air at 20ºC moves at 5 m/s in cross flow over the tubes. Each tube is 1 m long and has an outside diameter of 10 mm. The tubes are in a square, aligned array with S_T=S_L=15 "mm" . Properties: At 20ºC, rho=1.164 "kg/" "m" ^"3" , c=1012 "J/kgK" , k=0.0251 "W/mK" , α=22×10^(-6) "m" ^"2" "/s " , μ=18.240×10^(-6) "Ns/" "m" ^"2" , ν=15.7×10^(-6) 〖" m" 〗^"2" "/s" , Pr=0.71. At 100ºC, Pr=0.70. a) Find q, the rate of heat transfer to the air
