Oil (s=0.80) and viscosity (u = 0.098 Pa – sec) flow from a reservoir of surface elevation 100 meters to one with a surface elevation of 94 meters through a 150 mm Ø smooth pipe width is 300 meters long. Determine the average velocity in the pipe. %3D

Oil having sp. gr. of 0.9 and viscosity v 0.0002 m2/s flows upward through an inclined pipe as shown. Determine the flow rate. Ans. 7.64 L/s 6 cm diameter P2 250 kPa 40 Pi 350 kPa

1- Water flows through a horizontal pipe at a rate of 9.1 L/s. The pipe consists of two sections of diameters 10.16 cm and 5.08 cm with a smooth reducing section. The pressure difference between the two pipe sections is measured by a mercury manometer. Neglecting frictional effects, (a) determine the differential height of mercury between the two pipe sections. (b) How would the reading change if the manometer on the 2in pipe is replaced by a pitot tube? 10.16 5.08 h
