A pipe is 26.0 m long and 4.0 cm in inner diameter, with walls 1.5 mm thick. If air at 20 °C and 105 Pa absolute pressure flows through the pipe with a velocity of 10.0 m/s, then . . . What is the pipe cross section area (m2)? What is the volumetric flow rate of air (m3/s)? What is the gas density (kg/m3)? What is the mass flow rate of air (kg/s)? What is the air molecular mass (kg/mol)?...
A flow nozzle equipped with a differential pressure gage is used to measure the flow rate of water at 10°C (p 9997 kg/m3 and p 1.307 x 10-3 kg/m s) through a 3-cm-diameter horizontal pipe. The nozzle exit diameter is 1.5 cm, and the measured pressure drop is 3.3 kPa. Determine the volume flow rate of water, the average velocity through the pipe, and the head loss 1.5 cm Differential pressure gage -3 m3(s m/s The volume flow rate of...
Water flows in a 7.4 cm diameter pipe at a velocity of 0.67 m/s. The mass flow rate in kg/s of water in the pipe is:
Air enters a 16-cm-diameter pipe steadily at 200 kPa and 20°C with a velocity of 5 m/s. Air is heated as it flows, and it leaves the pipe at 180 kPa and 38°C. The gas constant of air is 0.287 kPa·m3/kg·K. Whats the volumetric flow rate of the inlet/outlet, mass flow rate and velocity & volume flow rate at the exit?
A) Steam enters a horizontal pipe operating at steady state with a specific enthalpy of 2,663 kJ/kg and a mass flow rate of 0.1 kg/s. At the exit, the specific enthalpy is 1,531 kJ/kg. If there is no significant change in kinetic energy from inlet to exit, determine the rate of heat transfer between the pipe and its surroundings, in kW. B) Refrigerant 134a enters a horizontal pipe operating at steady state at 40°C, 3.1 bar and a velocity of...
Water (density = 1000 kg/m3) flows through a 0.30-m-diameter pipe at 1.5m/s. What is the mass flow rate of water?
Water at 20°C flows in a steel pipe whose diameter is 26.65 mm. The volume flow rate of the water in the pipe is measured to be 3.155 x 10-4 3/s. The density at this temperature is given as 998.2 kg/m3. The mass flow rate is: m 0.315 kg/s | 1.22 kg/s O 0.522 kg/s O 0.575 kg/s 0.419 kg/s Previous Page Next Page Page 8 of 25

Fluid flows at 2.5m/s through a 0.20-m-diameter pipe. What is the volume flow rate?
Determine the velocity of fluid in m/s at the throat (at the smaller diameter of the pipe), and the mass flow rate of the fluid at the inlet, if the flow is coming from left to right in a system as shown below. Specific gravity of the flowing fluid is 1.2, and density of water is 1,000 kg/m^3. Find: A) velocity of fluid (m/s) at the throat, & B) mass flow rate of the fluid at the inlet. P1 =...
