A 2.5-cm-diameter horizontal water jet with a speedof Vj 5 40 m/s relative to the ground is deflected by a 60°stationary cone whose base diameter is 25 cm. Water velocityalong the cone varies linearly from zero at the cone surfaceto the incoming jet speed of 40 m/s at the free surface. Disregarding the effect of gravity and the shear forces, determinethe horizontal force F needed to hold the cone stationary.
