Force and pressure on a wall by a jet of water

This video tries to determine the magnitude of force and pressure on a wall when a jet of water strikes it normally.

Why is this different than drag force with the 1/2 value added? Assuming Cd=1

Hi Sajit, can you help with eductor nozzle calculation if it get installed at 10: hose and head pressure can be developed?
Thanks

A jet of water with area of cross section 2cm^2 strikes a wall at an angle 60 degree to the normal and rebounds elastically from the wall with the same speed. If the speed of water in the jet is 10 m/s, find the force acting on the wall.
Sir, please tell me how to solve such question in which angle with which the water column strikes on the wall is given??
