Question 4 a. The data below are obtained from a Reynolds Number test: Water temperature at the beginning of the experiment = 25 °C; • Water temperature at the end of the experiment = 30 °C; • Volume of water collected in 25 seconds = 240 ml; • Pipe diameter, d = 10 mm.

A mercury Manometer is attached to a pipe having suction pressure. The right limb is open to the atmosphere while the contact between mercury and water is in left limb at a distance of 30 cm from the center of the pipe. a. If the difference in the Level of mercury in the two limbs is 20 cm, What will be the pressure in the pipe. b. If the pressure in the pipe is increase to Pascal, What will be the new difference in mercury level?

Consider oil flowing through a horizontal pipe at a rate of 3 liter/s. There are two sections of the pipe with diameters 10 cm and 7 cm and the two sections are connected by a smooth reducing section as shown in the schematic. We use a manometer with glycerin as the manometer fluid (with glycerin density of Pglycerin 1,260 kg/m³) to measure the pressure difference between the two pipe sections. Assume that frictional effects are negligible and consider specific gravity of oil as SGoil = 0.76. What is the manometer reading, h (i.e. differential height of glycerin between the two arms of the manometer)? 10 cm I h T 7 cm-
