1.8. A liquid, like the one shown, forms a convex meniscus inside a Convex meniscus glass capillary tube if: a) the pressure inside the glass tube is higher than the pressure outside the tube. b) the density of the liquid is greater than the density above the meniscus. c) the hydrostatic pressure of the liquid is very large. d) the surface tension of this liquid is less than the surface tension of water. e) the surface tension of this liquid is greater than the surface tension of water. The pipe shown below is horizontal, has constant diameter, and carries incompressible fluid in a steady flow from left to right. 2 1.9. In the pipe above, Bernoulli's equation predicts the relationship between the pressures at 1 and 2 to be: a) P1=P2 b) P1>P2 c) PIVI e) P2>PI 1.11. A water jet strikes a stationary vertical plate horizontally at a rate of 7 kg/s with a velocity of 35 km/h. Assume the water stream moves in the vertical direction after the strike. The force needed to prevent the plate from moving horizontally is: a) 24.3 N b) 35.0 N C) 48.6 N wonyoud to d) 68.1 N e) 79.3 N
