Three different fluids are used in the manometer shown here. PL P2 PA* hi -PB U Th{| Pc Expression for P1 - P2 Correct Which of the following expressions correctly represents the quantity P1 - P2? gh1(B-PA) + ghalec-PA) Example Calculation * If you applied the correct formula from above, then there is probably a problem of unit conversions. Suppose fluid A is methanol, B is water and Cis a manometer fluid with a specific gravity of 1.30; pressure P2 = 133.0 kPa; h1 = 36.0 cm; and h2 = 27.0 cm. Calculate P1. P1 = i 41909 kPa Hint Save for Later Attempts: 1 of 3 used Submit
