Quiz A fluid of density 1421.5 is used in a manometer across an orifice in a water pipeline. The reading shown here is obtained. 1. What is the pressure drop (Ib; /ft) from point (a) to point (b)? 2. What is the pressure drop from point (a) to point (b) in (mm Hg) if the fluid is mercury (Hg)? 26 cm

Given information is attached. A. Neglect friction and calculate the velocity at point 2. (Velocity in m/s) B. If the pipe diameter at point 2 is 7.00 cm, what is the diameter at point 1? (Diameter in cm)

A pipeline conveys benzene from one point to the other. A gauge attached to line reads 150kPa. It is desired to check the gauge reading with benzene –over-mercury U-tube manometer.Determine the expected height difference of the mercury in the manometer; if on one endthe manometer is open to the atmosphere and on the other end where the gauge pressure isconnected there is a 3 cm height of benzene above the mercury meniscus. (benzene densityis 876 kg/m3 and mercury 13600 kg/m3)
