1- Water flows steadily through a horizontal bend with circular cross section and discharges into the atmosphere as shown in the figure below. If the gage pressure is Pgage=62 kPa and the flow rate Q is 0.12 m/s a) Sketch the control volume; show the unit area vectors and velocities at the inlet and outlet; show forces on the control volume, b) Determine the (x) component of the force that the water exerts on the bend, c) Determine the (y) component of the force that the water exerts on the bend. Note: The density of water pwater is 1000 kg/m Pgage=62 kPa Bend The Mass and Linear Momentum Conservation Equations for a fixed control volume are: Water 0.06 m Area 0.03 m 2 FAy = ? 45 F= ? |_ p(V + n) dA = 0 Le dv + L pl at (Vpdy) + Vp(Vn) d dA
