• FT

• FP

• FB

• FR

What is the total force, FT, given by the sum of?

• FR, FB, FP

• FR, FB, FP, FV

• FR, FB, FP, FC

What is the force due to the flow around a pipe bend?

• FP

• FB

• FR

• FT

What is the control volume drawn in the analysis?

• With faces at the inlet and outlet of the bend and encompassing the pipe walls

• With faces at the inlet and outlet of the bend only

• With faces at the inlet of the bend only

• With faces at the outlet of the bend only

What is the resultant force on the fluid given by?

• FT = FR + FB + FP

• FT = FR / FB / FP

• FT = FR - FB - FP

• FT = FR * FB * FP

What is the force required to keep the plate moving at constant velocity if the jet density is 1000 kg/m3, the jet area is 3 cm2, and Vj and Vc are 20 and 15 m/s, respecƟvely?

• Rx = 0, Ry = 18.5 N

• Rx = 18.5 N, Ry = 7.1 N

• Rx = 7.1 N, Ry = 18.5 N

• Rx = 18.5 N, Ry = 0
