A liquid comes out of the reactor of a chemical plant at $250^{\circ} \mathrm{C}$ temperature with a flow rate of 100 LPM . The ambient temperature is $25^{\circ} \mathrm{C}$. Density and specific heat of the liquid remain constant at $1000 \mathrm{~kg} / \mathrm{m}^3$ and $4.18 \mathrm{~kJ} / \mathrm{kg} \mathrm{K}$, respectively, for the given range of temperature. The rate of exergy associated with the hot liquid stream at the exit of the plant is $\_\_\_\_$ kW (rounded off to 2 decimal places).

The pressure, temperature and velocity of air flowing in a pipe are $$5$$ $$bar,$$ $$500$$ $$K$$ and $$50$$ $$m/s,$$ respectively. The specific heats of air at constant pressure and at constant volume are $$1.005kJ/kgK$$ and $$0.718$$ $$kJ/kgK,$$ respectively. Neglect potential energy. If the pressure and temperature of the surroundings are $$1$$ bar and $$300$$ $$K,$$ respectively, the available energy in $$kJ/kg$$ of the air stream is

$$A$$ gas expands in a frictionless piston-cylinder arrangement. The expansion process is very slow, and is resisted by an ambient pressure of $$100kPa.$$ During the expansion process, the pressure of the system (gas) remains constant at $$300$$ $$kPa.$$ The change in volume of the gas is $$0.01{m^3}.$$

The maximum amount of work that could be utilized from the above process is

$$0$$ $$kJ$$

$$1$$ $$kJ$$

$$2$$ $$kJ$$
