A pressure gage at elevation 10 m at the side of tank containing a liquid reads 80 kpa. Another gage at elevation 4 reads 120 kPa. Find the specific gravity of the liquid. a. 0.52 b. 0.65 c. 0.68 d. 0.73

-8.33 -0.12 8.33 (1) 0.12 -L Darcy Experiment A set-up of Darcy Experiment involves measuring the pressure head at two piezometers separated a distance, L. Given the set-up shown, determine the hydraulic gradient if the hydraulic head at (1) is 66 cm, hydraulic head at (2) is 54 cm, and the travel distance is 100 cm. h (2) e - - - -

For the open tank, the piezometers attached on the side, containing two different immiscible liquids, as shown in the figure, find the elevation of the liquid surface in piezometer A.

3. What is the pressure difference between pipe A and pipe B? Give pressure difference in kPa. (y = 1.22 m and h 30 in.) The gage fluid, M, is mercury with a specific gravity of 13.54 State assumed values if any. Water A Water B y D Liquid M
