Air at T1 = 300 K, p1 = 303 kPa, and V1 = 0.5 m/s enters the Venturi shown in Fig. P5.43. The air leaves at T2 = 220 K and p2 = 101 kPa; A1 = 0.6 m2 and A2 = 1.0 m2. Calculate the horizontal force required to hold the Venturi stationary.

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.
