Compare the total momentum before and total momentum after of elastic and perfectly inelastic collision. Compare the total KE before and total KE after of elastic and perfectly inelastic collision.

A jet impinges on a splitter block. The incoming jet is horizontal and has a flow rate of Q1 = 8000 cm³/s and a cross-sectional area of A1 = 40 cm?. The block splits the jet in to two smaller jets. One is deflected upward by 45°, and has a flow rate of Q2 = 6000 cm3/s and a cross-sectional area of A, = 30 cm2. The other jet is deflected downward by 45°, and has a flow rate of Q3 = 2000 cm³/s and a cross-sectional area of A3 = 10 cm2. You may assume that the pressure everywhere is equal to atmospheric pressure, and the density of the fluid is 1000 kg/m³. Q2= 6000 cm³/ A,= 30 cm2 Q,= 8000 cm³/s %3D e = 45° e = 45° A,= 40 cm² A3= 10 cm2 Q3= 2000 cm3/s
