Assignment -1. To be submitted in Assignment book on 24 – 06 – 13 (Monday). Write Name and Register No: in the Assignment book. Draw neat Diagrams , charts, if any. For Sl/No: 1117139, 1117551 – 1117562 Qn. – 1: A gas is stored in a reservoir at temperature 300 K. Determine the stagnation enthalpy. For the gas, ratio of sp. heats, γ = 1.4 and molecular wt. = 29.94 Qn. – 2: Air flows through an air turbine rotor where the stagnation pressure drops at a rate 5:1.5. Total to total efficiency is 0.82 and the air flow rate is 5 kg/S. If the total power output is 450 kW, ratio of sp. heats, γ = 1.4 and sp. heat at constant pressure, Cp = 1004 J/kgK, find: (1) inlet total temperature, (2) actual exit total temperature if exit velocity is 150 m/S , (3) actual exit static temperature and (4) total to static efficiency. For Sl/No: 1117563 – 1117578 Qn. – 1: A gas is stored in a reservoir at temperature 400 K. Determine the stagnation enthalpy. For the gas, ratio of sp. heats, γ = 1.35 and molecular wt. = 27 Qn. – 2: Air flows through an air turbine rotor where the stagnation pressure drops at a rate 6:1.5. Total to total efficiency is 0.78 and the air flow rate is 5.5 kg/S. If the total power output is 350 kW, ratio of sp. heats, γ = 1.4 and sp. heat at constant pressure, Cp = 1004 J/kgK, find: (1) inlet total temperature, (2) actual exit total temperature if exit velocity is 150 m/S , (3) actual exit static temperature and (4) total to static efficiency. For Sl/No: 1117579, 580, 1158509, 1158501 – 1158511 Qn. – 1: A gas is stored in a reservoir at temperature 500 K. Determine the stagnation enthalpy. For the gas, ratio of sp. heats, γ = 1.35 and molecular wt. = 37 Qn. – 2: Air flows through an air turbine rotor where the stagnation pressure drops at a rate 8:1.5. Total to total efficiency is 0.85 and the air flow rate is 6.5 kg/S.
