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 equation
The 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.
(Continuity, momentum, and energy equation)

However, during this process, the worker is lifted by the jet of water exiting a 30 cm diameter hole in the pipe. If the worker has a mass of 90 kg, determine the flow rate Q required to exit the hole in the pipe to keep the worker airborne. Assume that the jet maintains the same diameter as the hole and that, upon interacting with the worker, it takes a completely horizontal direction before falling to the ground.arrow_forward

Along the centerline of the diffuser, the air speed decreases from entrance to exit as sketched. For the velocity field, calculate the fluid acceleration along the diffuser centerline as a function of x and the given parameters. For L = 1.56 m, entrance = 21.00 m/s, and exit = 17.5 m/s, calculate the acceleration at x = 0 and x = 1.0 m. Dexis Dentrance x=0 u(x) "exit "entrance x=L The acceleration at (x = 0) is -47 m/s². The acceleration at (x = 1.0 m) is 42.1 m/s.

The room is heated by a heat pump so that the temperature distribution at steady state is T(x, y, z) = (400–0.2(5x) 2-0.4y-0.6%) ˚C. Calculate the temperature change that the bird feels after 10.00 seconds of flight, as it flies through x = 1m. (Round the final answer to three decimal places.) The temperature change that the bird feels after 10.00 seconds of flight is 1.120 °C/s.arrow_forward
