please answer all thank you so much

PROBLEM 1: An open test tube at 293 K is filled at the bottom with 11.7 cm Hg and 6.4 cm of water placed above the Hg. Calculate the pressure (a) in psi and (b) in kPa at the bottom of the test tube if the atmospheric pressure is 750 mmHg. Use a density of 13.6g/cm3 for Hg and 0.998g/cm3 for water. (20 points) PROBLEM 2: The pressure at the top of a tank of jet fuel is 180kN/m2. The depth of liquid in the tank is 6.4 m. The density of the fuel is 825kg/m3. Determine the head of the tank the liquid in feet which corresponds to the absolute pressure at the bottom of the tank. (20 points) PROBLEM 3: The two-fluid U-tube manometer is being used to measure the difference in pressure at two points in a line containing air at 1 atm absolute pressure. The lighter fluid is a hydrocarbon with density equals to 812kg/m3 and the heavier water with density equals to 998kg/m. The inside diameters of the U tube and reservoir are 3.2 mm and 54.2 mm, respectively. The reading of the manometer is 120.0 mm. Use the formula Pa - Pg = R(pa - pb) where a and b are the two different fluids and R is the manometer reading. Calculate the pressure drop in (a) mmHg and (b) Pa. (20 points)
