A sealed adiabatic piston/cylinder system is used to compress nitrogen gas (γ = 1.4, ¯m = 28.0 kg/kmol) from T1 = 300 K and p1 = 1.0 bar to a final pressure of p2 = 10 bar. Assume a calorically perfect gas over the temperature range of interest. (a) What is the minimum amount of specific work (wₘᵢₙ) required to achieve this compression? (b) The measured final temperature is T2 = 590 K. If the efficiency is defined as: η = wₘᵢₙ / wₐₜᵤₐₗ , what is the efficiency of this compression process?

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
