Question: Force to open a rectangular gate: A rectangular gate ( 5 m 4 m ) covers the end of a circular pipe 4 m in

Force to open a rectangular gate:
A rectangular gate (5m4m) covers the end of a circular pipe 4m in diameter. If the gate is hinged at
the top, what normal force F is required to open the gate when water is 8m deep above the top of the
pipe and the pipe is open to the atmosphere on the other side?
Neglect the weight of the gate, and neglect friction between the bottom on the gate and the pipe wall.
Assume water temperature is 10 degrees Celsius.
