Question: A glass tube with inside diameter 150 m is placed in a water bath. (a) How high will the water rise inside the tube? Give

A glass tube with inside diameter 150 μm is placed in a water bath.

(a) How high will the water rise inside the tube? Give your answer in cm.

(b) What will the water pressure be halfway between the free water surface and the water level in the tube (i.e., at hc/2)? Give your answer in kN/m2.

(d) What air pressure (+ or -) would have to be applied to the tube to get the water in the tube to rise 25 cm above the free water surface? Give your answer in kN/m2.?
