Chapter 10, Problem 10.13P

Consider a rocket engine burning hydrogen and oxygen. The total mass flow of the propellant plus oxidizer into the combustion chamber is 287.2 kg/s. The combustion chamber temperature is 3600 K. Assume that the combustion chamber is a low-velocity reservoir for the rocket engine. If the area of the rocket nozzle throat is 0.2 m 2 , calculate the combustion chamber (reservoir) pressure. Assume that the gas that flows through the engine has a ratio of specific heats, γ = 1 . 2 , and a molecular weight of 16.

In a reaction stage of a stcam turbine the nozzle angle is 20° and the absolute velocity the steam at inlet to the moving blades is 240 m/s. The blade velocity is 210 m/s. If 1.7 the blading is designed for 50% reaction, determine: (i) the blade angle at inlet and exit; il the cathalpy drop per unit mass of steam in the moving blades and in the complete stage; (i) the diagram power for a steam flow of 1 kg/s: (iv) the diagram efficiency. (79.3, 20°; 25.3 kJ/kg; 50.6 kJ/kg; 50.6 kW; 93.5%)
If the calculated mass flow rate of petrol fuel is 9.25 x 10-5 kg/s, what is the time taken for the 10 mL of petrol fuel been supplied into the engine? Note that the calorific value and density of the petrol fuel are 43 MJ/kg and 712 kg/m3 respectively.
Find the boiler chimney diameter if the boiler has a capacity of 320 kW with a combustion efficiency of 75%, and uses diesel as fuel with a calorific value of 40000 kJ/kg. Assume the flue gases density as 1.12 kg/m3 and moving with a velocity of 4 m/s.
