- The temperature of feed water can be increased in following two ways in a regenerative Rankine cycle i) by passing feed water around turbine casing in direction opposite to flow of steam ii) by bleeding certain portion of steam at the end of h.p expansion & mixing with condensate to make feed water at the temperature of boiler
- Correlate the following statements i) the volume of water into which steam is condensed in condenser is very much smaller than the volume of steam before condensation ii) the net work of a Rankine cycle is heat supplied in boiler - heat rejected to condenser - pump work
- A rigid tank contains 10 kg of water at 90°C. If 8 kg of the water is in the liquid form and the rest is in the vapour form, determine the volume of the tank.
- The temperature at which the volume of a gas becomes zero is called
- ………. Law states that equal volume of all gases, at the same temperature & pressure, contains equal number of molecules
- Variations of pressure & volume at constant temperature are correlated through
- During a polytropic expansion 25% of heat is converted into work while temperature of gas rises by 30 K, the specific heat of gas at constant volume is
- 90 g glucose is filled in a container at 10 atm, if the volume of container is 2 liter, what is the temperature of glucose (z = 1.5)?
- Whenever heat is transferred through a finite temperature difference, there is always a decrease in the availability of energy so transferred.
- During an adiabatic compression when temperature increase by 100% the pressure increases by 1000%. The ratio of specific heats, ? is
