A T-shaped venturi tube is placed in a tub of water. There is a stream of air that is passing through the horizontal part of the tube (i.e., both ends of the "T" are open). For this question assume that g is 9.81 m/s², the density of water is 1000 kg/m³, density for air is 1.23 kg/m³, and atmospheric pressure is 101325 Pa.

If the height difference between the water levels inside and outside of the venturi tube is 6.00 cm, what is the magnitude of the difference in air pressure inside and outside of the venturi tube in Pa? _______ Pa

What is the speed of the air flowing through the venturi tube to cause this pressure difference? You may assume that atmospheric pressure does not change depending on height. _______ m/s
