of mercury.

b. At time t later, the air speed is known to flow through the tube
from left to right at a rate of 1200 cm³/s. Draw three air
streamlines through the tube. Interpret what these lines are

A jet of water with a diameter of 100 mm flows vertically until it meets a solid vane that deflected it at an angle of 180°. The initial velocity of the jet is 20 m/s. As a result of friction, the velocity of the jet leaving the vane is 15 m/s. Assuming the fluid is at atmospheric pressure throughout and neglecting the gravity effects, calculate the magnitude of the force exerted by the water on the vane. (water density 1000 kg/m3)
A water jet is releasing a discharge of 13.20 gallon per second from a 60 mm diameter nozzle inclined at a certain angle with the vertical. Neglecting air resistance, the jet just passed over the top of a wall 25 meters horizontally away and 5.30 meters above the nozzle tip. How far will the water jet travel from the releasing point to the dropping point on the ground? Assuming the water will not spread-out on the ground.

This expression should give v in terms of the vertical height y and the acceleration due to gravity g.
