A pair of vertical, open-ended glass tubes inserted into a horizontal pipe are often used together to measure flow velocity in the pipe, a configuration called a Venturi meter. Consider such an arrangement with a horizontal pipe carrying fluid of density ρ. The fluid rises to heights h1 and h2 in the two open-ended tubes (see figure). The cross-sectional area of the pipe is A1 at the position of tube 1, and A2 at the position of tube 2.

Part B
Find v1, the speed of the fluid in the left end of the main pipe.
Express your answer in terms of h1, h2, g, and either A1 and A2 or γ, which is equal to A1A2.


question 2- What is the gas pressure inside the box shown in the figure? (Figure 1)
Express your answer using two significant figures.

question 3-You are assigned the design of a cylindrical, pressurized water tank for a future colony on Mars, where the acceleration due to gravity is 3.71 meters per second per second. The pressure at the surface of the water will be 140kPa , and the depth of the water will be 13.8m . The pressure of the air in the building outside the tank will be 87.0kPa .

Part A
Find the net downward force on the tank's flat bottom, of area 1.90m2 , exerted by the water and air inside the tank and the air outside the tank.
Express your answer numerically in Newtons, to three significant figures.
