DifferentialManometer (Numericals 1): 1. A U-tube monometer is used to measure the pressure of oil (specific gravity 0.85) flowing in a pipe line. It's left end connected to pipe and right limb is open to the atmosphere. The centre of pipe is 100 mm below the level of mercury in the   right limb. If the difference of mercury level in the two line is 160 mm, then determine the head and pressure. Solution :          h = 13.6 x 160 x 10 -3 x 0.85 x60 x 10 -3                            = 2176 x 10 -3  x 51.00 x 10 -3                            = (2176-51) x 10 -3                     ...
