Sample ME8595 Important 8 marks Questions THERMAL ENGINEERING II
(a) Mention the types of nozzles you know, Where are these used?
(b) Steam having pressure of 10.5 bar and 0.95 dryness is expanded through a convergent-divergent nozzle and the pressure of steam leaving the nozzle is 0.85 bar. Find the velocity at the throat for maximum discharge conditions. Index of expansion may be assumed as 1.135. Calculate mass rate of flow of steam through the nozzle.

(a) Dry saturated steam enters a frictionless adiabatic nozzle with negligible velocity at a temperature of 300oC. It is expanded to pressure of 5000 KPa. The mass flow rate is 1 kg/s. Calculate the exit velocity of the steam.
(b) Steam is expanded in a set of nozzles from 10 bar and 200oC to 5 bar. What type of Nozzle is it? Neglecting the initial velocity find minimum area of the nozzle required to allow a flow of 3 kg/s under the given conditions. Assume that expansion of steam to be isentropic.

In a steam nozzle, the steam expands from 4 bar to 1 bar. The initial velocity is 60 m/s and the initial temperature is 200oC. Determine the exit velocity if the nozzle efficiency is 92%.
Describe (Derive) the expression for critical pressure ratio in terms of index of expansion. ME8595 Important 8 marks Questions THERMAL ENGINEERING II
Dry saturated steam enters a steam nozzle at a pressure of 15 bar and is discharged at a pressure of 2 bar. If the dryness fraction of discharge steam is 0.96, what will be the final velocity of steam? Neglect initial velocity of steam. If 10% of heat drop is lost in friction, Examine (find) the percentage reduction in the final velocity.
