Oil flows through the 100-mm-diameter pipe with a velocity of 8 m/s
(Figure 1). The flow occurs in the horizontal plane. Take p = 900 kg/m³.
▼
Part A
If the pressure in the pipe at A and B is assumed to be 90 kPa, determine the component of force the flow exerts on the elbow.
Express your answer to three significant figures and include the appropriate units.

▾ Hint 1. How to determine the component of force the flow exerts on the elbow
Build a free body diagram of the control volume containing oil within the pipe and elbow between cross-sections at A and B. Then using the linear momentum equation
determine the component of the force the flow exerts on the elbow.
