- A horizontal pipe network has a connection of three pipes of different diameters, where the flow in section 3 exits to the atmosphere. The following requirements are required: a) Outlet flow rate at point 3. b) Pressure at point 2. c) x and y components of the force the flow exerts on the connection. Continuity, momentum, and energy equationarrow_forwardThe expression "flush" comes from the fact that the first toilet tanks were quite high, and you literally had to flush the toilet to move the stopper and flush the water. If the water level inside the tank is 1.8 m high and the pipe diameter is 5 cm, determine the following: a) The velocity of the water entering the toilet. b) The force at the junction of the pipe and the toilet, which is required to prevent the pipe from coming out and spilling water onto the floor.
