6. Discussion: 1. Is there a difference between the values of the nozzle velocity (vn) and the jet velocity (v₁)? Why? 2. Is there a difference between the values of the water jet force on plate (F₁) when change the plate shape (flat, Conical, and Hemispherical plate)? Why? 3. Is there a difference between the values of the water jet force on plate (F₁) and the force exerted by weights on fluid (Fexp)? Why? 4. What is the relationship type in the plot between (Fexp) versus (p Qv₁)? Why? 5. Is there a difference between the slope from plot and the slope of the value (1- Cose)? Why?
