The differential change in pressure p close to the surface of a static fluid is given by the following expression: dpidy-34p where A is a constant, with units of 1/(atm-m), and p is the pressure in atm. The pressure at the surface of the fluid is p(0) = 1 atm, and the coordinate y here is positive upwards with origin at the surface. (a) Write an expression for the absolute pressure as a function of y. 50% Part (b) An absolute pressure gauge is placed at a depth 0.12 m in the fluid. What would be the reading of the pressure gauge in units of atm? You can take the constant A = 1 (atmm). p=
