Also asked in Summer 2026 Q1c
Derive an expression for the velocity in terms of enthalpy drop for a flow through nozzle.
The pressure and temperature of steam entering nozzle are 12 bar and 200°C and steam leave nozzle at 1 bar. The diameter of the nozzle at the throat is 10 mm. Calculate the mass flow rate of steam in a nozzle. Comment on type of nozzle required.
Derive an expression for maximum efficiency for a single stage impulse steam turbine.
With help of neat sketch and chemical reactions explain working of Zeolite ion exchange process.
A mean blade ring diameter of a single stage impulse turbine is 1.3 m. It runs at 3200 rpm. The nozzle angle is 15° and blade speed ratio is 0.45. The blade friction factor is 0.9 and discharge is axial. Calculate blade inlet and outlet angles and power output per kg of steam.
The effective jet velocity from a rocket engine is 2900 m/sec. The forward velocity is 1450 m/sec and the propellant consumption is 78 kg/sec. Calculate thrust, thrust power and propulsive efficiency.
A gas turbine operates on Brayton cycle. The temperature range is 1050 K and 288 K. Find pressure ratio for maximum power output. Also determine thermal efficiency, work ratio and power output, if mass flow rate of air is 20 kg/sec. Take Cp=1.005 kJ/kg K and γ=1.4 for compression and expansion process.
