1.A 4-m- long, 6-cm-diameter cylinder placed normal to the flow is used to measure the velocity of an air stream. If a force of 50N is measured. What is the air velocity in m/s?
2.A syringe is pointed vertically up in the air and a force of 5 lbs is applied to the plunger with a diameter of 0.5 inches.
Assuming no losses in the system how high will the stream of water rise above the syringe (assume the height of the needle is negligible).
