Which equation represents the steady flow system?

$$H_{1} + \frac{V_{1}^{2}}{2gJ} + \frac{Z_{1}}{J} + Q = \frac{V_{2}^{2}}{2gJ} + \frac{Z_{2}}{J} + Losses$$

$$H_{1} + \frac{V_{1}^{2}}{2gJ} + \frac{Z_{1}}{J} + Q = \frac{V_{2}^{2}}{2gJ} + \frac{Z_{2}}{J} + Losses + Work done$$

$$H_{1} + \frac{V_{1}^{2}}{2gJ} + \frac{Z_{1}}{J} + Q = H_{2} + \frac{V_{2}^{2}}{2gJ} + \frac{Z_{2}}{J} + Losses + Work done$$

$$H_{1} + \frac{V_{1}^{2}}{2gJ} + \frac{Z_{1}}{J} = H_{2} + \frac{V_{2}^{2}}{2gJ} + \frac{Z_{2}}{J} + Losses + Work done$$
