A gas is flowing through a horizontal pipe of cross section area of 30 cm2 at a point the pressure is 30 N/cm2 and temperature is 20°C. At another section, the area of cross section is 15 cm2 and pressure is 25 N/cm2. If the mass rate of flow of the gas is 0.15 kg/s, calculate the velocities at these two sections, assuming an isothermal change take R=287 J/kg.K and atmospheric pressure 10 N/cm2. Both the pressures are the gauge pressure.

The space between two square flat parallel plates filled with oil. Each side of the plate is 720 mm. The thickness of the oil film is 15 mm. The upper plate which moves at 3 m/s requires a force of 120 N to maintain the speed. Determine: a) The dynamic viscosity of oil. b) The kinematic viscosity of oil if the specific gravity of oil is 0.95

An inverted U-tube manometer is connected to two horizontal pipes A and B through which water is flowing. The vertical distance between the axes of these pipes is 30 cm. when an oil of specific gravity 0.8 is used as a gauge fluid, the vertical heights of water columns in the two limbs of the inverted manometer (when measured from the respective centre lines of the pipes) are found to be same and equal to 35 cm. determine the difference of pressure between the pipes

A 40 cm diameter pipe, conveying water, branches into two pipes of diameter 30 cm and 20 cm respectively. If the average velocity in the 40 cm diameter pipe is 3 m/sec, find the discharge in this pipe. Also determine the velocity in 20 cm diameter pipe if the average velocity in 30 cm diameter pipe is 2 m/sec.
