When_p. = p. the levels in the reservoir and tube are at the null plane. As a pressure difference is imposed on fluid B, the manometer fluid A is forced downward in the reservoir and upward in the tube. The length of movement along the tube is the scale reading. R. The cross-sectional area of the reservoir is 4, and that of the tube is.. 4. (a) Derive the manometer equation in its complete form. [Equation (2.11) of MSH textbook is only exact in the limiting case 4/4 ) (b) At what value of 41 A, does P.-P. calculated by means of Equation (2.11) differ from P.-P. calculated by means of the equation of part (a) by 5.0 percent of the latter when the angle a is 30?
