Oil with a density of and kinematic viscosity of is being discharged by a 8-mm-diameter, 40-m-long horizontal pipe from a storage tank open to the atmosphere. The height of the liquid level above the center of the pipe is 4 m. Disregarding the minor losses, determine the flow rate of oil through the pipe.
Step 11 of 4
We have steady and incompressible flow. The entrance effects are negligible, so the flow is fully developed. The entrance and exit loses are alos negligible.
First step is to calculate pressure at the bottom of the tank:
Disregarding inlet and outlet losses, the pressure drop across the pipe is:

The air velocity in the duct of a heating system is to be measured by a Pitot-static probe inserted into the duct parallel to the flow. If the differential height between the water columns connected to the two outlets of the probe is 2.4 cm, determine (a) the flow velocity and (b) the pressure rise at the tip of the probe. The air temperature and pressure in the duct are and 98 kPa, respectively.
Steam flows steadily through an adiabatic turbine. The inlet conditions of the steam are 4 MPa, 500C, and 80 m/s, and the exit conditions are 30 kPa, 92 percent quality, and 50 m/s. The mass flow rate of the steam is 12 kg/s. Determine (a) the change in kinetic energy, (b) the power output, and (c) the turbine inlet area. Answers: (a) -1.95 kJ/kg, (b) 12.1 MW, (c) 0.0130 m^2
