Explanation Draw the schematic diagram of the manometer as shown in figure (1). Manometer rule assumption: Adding the pressure while going downwards and subtracting the pressure while going upwards. Refer the figure (1), Apply the manometer rule for the given manometer before the elevation change. p A + γ H 2 O ( 18 in . ) − γ H g ( 6 sin30 ° in . ) − γ o i l ( 12 in . ) = p B p A + γ H 2 O ( 18 in . × 1 ft 12 in . ) − γ H g ( 6 sin30 ° in . × 1 ft 12 in . ) − γ o i l ( 12 in . × 1 ft 12 in . ) = p B p A + 1.5 γ H 2 O − 0.25 γ H g − γ o i l = p B (I). Refer the figure (1), Apply the manometer rule for the given manometer after the elevation change. p A ' + γ H 2 O ( 18 in .+ a ) − γ H g ( a + 6 sin30 ° in . + b sin30 ° in . ) − γ o i l ( 12 in . − b sin30 ° ) = p B p A + γ H 2 O ( 18 in . × 1 ft 12 in . + a ) − γ H g ( a + 3 in . × 1 ft 12 in . + b 2 ) − γ o i l ( 12 in . × 1 ft 12 in . − b 2 ) = p B p A + ( 1.5 + a ) γ H 2 O − ( 0.25 + a + 0.5 b ) γ H g − γ o i l ( 1 − 0.5 b ) = p B (II). Subtract Equation (I) from Equation (II), ( p A ' − p A ) + γ H 2 O ( a ) − ( a + 0.5 b ) γ H g + γ o i l ( 0.5 b ) = p B (III). The volume in the manometer is constant; it doesn’t change with respect to time. A 1 a = A 2 b π 4 ( 1 2 in ) 2 a = π 4 ( 1 4 in ) 2 b ( 1 2 in ) 2 a = ( 1 4 in ) 2 b b = 4 a Substitute 4 a in Equation (III)
