A U-tube manometer is attached to a 1 m diameter closed vessel and a pipe as shown. If the piston has a mass of 200 kg, a) Find the height, h, if the pressure at point A is 122 kPa higher than the reading on the gauge. b) If the pressure difference is decreased by 24 kPa, what is the new reading of h? c) If you want to play/practice, repeat problem (parts a and b) for the right branch of the u-tube manometer inclined to the right to 45 degrees with horizontal. What conclusions do you draw
