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/m³. 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 – P, = R(pa – Pb)g - 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.
