2. A cylindrical tank is filled with dimethylformamide (DMF,SG=0.944) up to a height of 3.75ft. The tank is open to the atmosphere and has a diameter of 4.00 feet. An open end mercury manometer is attached to the side of the tank. Assume the atmospheric pressure is 1atm and specific gravity of mercury is 13.6. c) What is the gauge pressure on the bottom surface of the tank (in ft water)? d) Supposing the distance d1 is equal to 0.5ft, what reading would you expect on the manometer, h (in mmHg )
