42. A liquid ( = 1.65 g/cm3) flows through two horizontal sections of tubing joined end to end. In the first section the cross-sectional area is 10.0 cm2 , the flow speed is 275 cm/s, and the pressure is 1.20 x 105 Pa. In the second section the cross-sectional area is 2.50 cm2. Calculate the smaller sections (a) flow speed and (b) pressure.
