Pipe bend fluid mechanics problem

[lukeg90]

Homework Statement

The pipe shown has a 180° horizontal bend in it as shown, and D is 20 cm. The
discharge of water (ρ = 1000 kg/m3)in the pipe and bend is 0.30 m3/s, and the
pressure in the pipe and bend is 100 kPa gage. If the bend volume is 0.10 m3 and
the bend itself weighs 500 N, what force must be applied at the flanges to hold the
bend in place?
