The resultant force the elbow exerts on the water and the direction of the resultant force.
Explanation of Solution
Draw the free body diagram of the pipe as in Figure (1).
Cross section of the both the end of the pipe are same
Calculate the area of pipe.
Calculate the velocity of pipe
Write the expression for the Equation for linear momentum:
Here, F is the force, cv is the control volume, V is the velocity,
Apply the Equation of equilibrium to obtain the horizontal force
Apply the equation of equilibrium to obtain the vertical force
Calculate resultant force the elbow exerts on the water
Thus, the resultant force the elbow exerts on the water
Calculate the direction of the resultant force
Thus, the magnitude
