For the following questions answer them individually
Which of the following processesis irreversible process?
General energy equation for system boiler is given by
In orast apparatus CuCl is used to absorb
General energy equation for a steady flow system is:
(a) $$H_1 + \frac{V_1^2}{2gj} + \frac{Z_1}{J} + Q = \frac{V_2^2}{2gJ} + Losses$$
(b) $$H_1 + \frac{V_1^2}{2gj} + \frac{Z_1}{J} + Q = \frac{V_2^2}{2gJ} + workdone + Losses$$
(c) $$H_1 + \frac{V_1^2}{2gj} + \frac{Z_1}{J} + Q = H_2 + \frac{V_2^2}{2gJ} + \frac{V_2}{J} + workdone + Losses$$
(d) $$H_1 + \frac{V_1^2}{2gj} + \frac{Z_1}{J} + Q = H_2 = \frac{V_2^2}{2gJ} + \frac{Z_1}{J} + workdone + Losses$$
The polytropic process on p-V diagram is represented by the figure.
In a throttling process, which one of the following parameters remains constant?
Zeroth law of thermodynamics states that
The heat absorbed or rejected during a polytropic process is equal to:
(a) $$\left(\frac{\gamma - n}{\gamma - 1}\right)^{\frac{1}{2}} \times workdone$$
(b) $$\left(\frac{\gamma - n}{n - 1}\right)^{\frac{1}{2}} \times workdone$$
(c) $$\left(\frac{\gamma - n}{\gamma - 1}\right) \times workdone$$
(d) $$\left(\frac{\gamma - n}{\gamma - 1}\right)^2 \times workdone$$
In a cycle, the heatis rejected at
