Onsider an air solar collector that is 1 m wide and 2 m long and has a constant spacing of 3 cm between the glass cover and the collector plate. air flows at an average temperature of 45°c at a rate of 0.12 m3/s through the 1-m-wide edge of the collector along the 2-m-long passageway. disregarding the entrance and roughness effects and the 90° bend, determine the pressure drop in the collector. the properties of air at 1 atm and 45° are ρ
