A sliding gate is installed in a rectangular channel with a horizontal bottom and a width of $250$ cm$.$ Upstream, the water depth is $230$ cm and downstream, $115$ cm$.$ Neglecting losses, calculate:

a$)$ The flow rate in the gate.

b$)$ The thrust on the gate. A sliding gate is installed in a rectangular channel with a horizontal bottom and a width of $250$ cm $.$ Upstream, the water depth is $230$ cm and downstream, $115$ cm $.$ Neglecting losses, calculate:
