What is the effect of compression ratio on efficiency of Otto cycle? What is meant by excess air? Never Miss. What is the use of junkers calorimeter? Petro chemical industry. What is meant by coming-in speed in gas turbines?

Scavenging is the process of forcing out the burnt exhaust gases from the cylinder by admitting the fresh charge into the cylinder. Mention the firing order of four cylinder internal combustion engines. Define brake power. Useful Power available at crank shaft is called as brake power. Mention any two unaccounted heat losses in heat engines. Heat lost due to radiation.

Heat lost due to exhaust gases. What is heat exchanger?

It is the apparatus which transfers minimum heat energy from a hot fluid to cold fluid. Define thermal conductivity. Thermal conductivity is the amount of heat flows in one second through a solid material of area 1 m2 and thickness of 1m when the change in temperature of faces is 1 C or K.

State zeroth law of thermodynamics. It states that, when two systems are separately in thermal equilibrium with a third system, then they themselves are in thermal equilibrium with a third system, then they themselves are equilibrium with each other. State STP condition. State any two examples of isolated system? Entire university Define Enthalpy. The combination of internal energy and flow energy is known as enthalpy of the system.

It is denoted by H. V kJ What is free expansion process? When a gas expands suddenly into a vacuum through a large orifice, free expansion occurs. Give two examples for reversible process. Piston and cylinder Shaping machine return mechanism. What is the effect of cut off ratio on efficiency of diesel cycle?

When the cut-off ratio increases, the efficiency of diesel cycle decreases. Define control surface? Control surface is the boundary of the control volume.

Write the general steady flow energy equation. Name the types of compression process used in air compression? Isentropic or Adiabatic compression.

Polytropic Compression. Isothermal compression. State the types of jet propulsion systems? Turbo jet units Turbo propeller units Ram-jet units State any two applications of rockets? Write the expression for theoretical minimum stoichiometric air required for complete combustion of 1Kg of fuel.

What is the use of junkers calorimeter? It is used to find calorific value of gaseous fuels. Mention two types of piston rings? Name the main elements of fuel supply system in petrol engines?

What are the various test conducted on an IC engines? Commercial test Thermodynamic test What is Morse test? Morse test is used to find indicated power of one cylinder on a multi cylinder.

Write the expression for heat conduction through a cylinder? Define black body? An ideal body which absorbs all the incident energy and neither reflects nor transmits any part of it. State the law of conservation of energy? It states that Energy can neither be created nor be destroyed, but it can be transferred from one form to another form Define Entropy.

Entropy is defined as a function of quantity of heat with respect to temperature. What is throttling process? When a gas or vapour expands and flows through an aperture of small size opening, the process is called throttling. Give two examples of irreversible process?

Throttling process. Free expansion process. Generation of heat by friction. What is the effect of compression ratio on efficiency of Otto cycle? Efficiency of otto cycle increases with increase in compression ratio. Define control volume? It is the system where volume is controlled by flowing of fluid by steady state. The control surface is the boundary of control volume. Write the steady flow energy equation for reciprocating air compressor.

State the disadvantages of single stage reciprocating air compressor? Handling of high pressure air results in leakage through the piston. Cooling of the gas is not effective. Requires a stronger cylinder to withstand high delivery pressure. How rotary compressors are classified?

Positive displacement air compressors. Non positive Dynamic air compressors.

State the methods for improvement of thermal efficiency of open cycle gas turbine plant. Intercooling improves thermal efficiency. What type of propellant is mostly used in rocket engine? Liquid propellant is mostly used in rocket engine. What is meant by excess air? In actual practice of engine, excess air than theoretical amount of air is called excess air. Write Dulongs formula for higher calorific value of fuel?

What is the purpose of connecting rod? It connects the piston and crank shaft. It transmits the force of explosion during power stroke to crank shaft. Name the main elements of fuel supply system in diesel engines. Classification — Components and their function. Valve timing diagram and port timing diagram — actual and theoretical p-V diagram of four stroke and two stroke engines.

Simple and complete Carburettor. MPFI, Diesel pump and injector system. Lubrication and Cooling systems. Performance calculation. Flow of steam through nozzles, shapes of nozzles, effect of friction, critical pressure ratio, supersaturated flow.

Impulse and Reaction principles, compounding, velocity diagram for simple and multi-stage turbines, speed regulations —Governors. Question Papers. Question Banks. Thank you for visiting my thread.
