A prankster, as shown in Figure I, has added oil, of specific gravity SG., to the left leg of the manometer at the right. Nevertheless, the U-tube is still to be used to measure the pressure in the air tank. (a) Find an expression for h as a function of H and other parameters in the problem. (b) Find the special case of your result when Ptank = Pa (c) Suppose H=5 cm, Pa = 101.2 kPa, SG = 0.85, and Ptank is 1.82 kPa higher than pi.
