A large pipe with a cross sectional area A1=1.2 m2 has water flowing through it. The pressure in the pipe there is maintained at atmospheric pressure. The pipe then descends 3.7 m and narrows to a new cross sectional area A2. Water exits the pipe there into an environment at atmospheric pressure. What must the cross sectional area A2 of the pipe be in m2 if the water is exiting the pipe with a speed of 9.8 m/s?
A liquid of density 830 kg/m3 flows through a horizontal pipe that has a cross-sectional area of 2.50 x 10-2 m2 in region A and a cross-sectional area of 9.20 x 10-2 m2 in region B. The pressure difference between the two regions is 6.80 x 103 Pa. What are (a) the volume flow rate and (b) the mass flow rate?
A liquid of density 930 kg/m3 flows through a horizontal pipe that has a cross-sectional area of 2.90 x 10-2 m2 in region A and a cross-sectional area of 9.90 x 10-2 m2 in region B. The pressure difference between the two regions is 7.40 x 103 Pa. What are (a) the volume flow rate and (b) the mass flow rate?
A liquid of density 890 kg/m3 flows through a horizontal pipe that has a cross-sectional area of 2.50 x 10-2 m2 in region A and a cross-sectional area of 8.50 x 10-2m2 in region B. The pressure difference between the two regions is 7.90 x 103 Pa. What are (a) the volume flow rate and (b) the mass flow rate?
Water is flowing through a horizontal pipe with an inside diameter of 8.00cm. The pipe narrows to an inside diameter of 3.75cm. Assume the water is an ideal incompressible fluid. What is the velocity of the fluid initially, v_1 (when It is flowing in the 8.00cm diameter section) if the velocity of the water in the narrow part of the pipe is measured at V_2 = 27m/s? If the initial pressure is known to be 670 kPa what is the...
a horizontal pipe has a cross sectional area of 40cm^2 at the wider portions and 10 cm^2 at the constriction. if the incompresible air flowing through the pipe with the inlet velocity of 1.5m/s at the wider cross section, what will be the flow velocity at the constriction?
Problem 15 Water flows through a horizontal pipe of cross-sectional area 10 cm3 at a pressure of 0.25 atm. The flow rate is 1.0 L/s. At a valve, the effective cross-sectional the valve? I area of the pipe is reduced to 5.0 cm. What is the pressure at A) 0.235 atm B) 0.200 atm C) 0.157 atm D) 0.112 atm E) 7.7x10 Pa
A column of water in a vertical pipe has a cross sectional area of 528 m2 and a weight of 0.2 N. (a) What is the increase in pressure (in Pa) from the top to the bottom of the pipe?
there is a velocity head flowing through a pipe with a calculated cross sectional area (6 inch schedule 460) If the pipe’s cross sectional area is doubled from calculated cross section to an unknown ft2 in, then calculate the velocity and velocity head. Note: acceleration due to gravity is 32 ft/s2
In a section of horizontal pipe with a diameter of 4.0 cm, the pressure is 47 kPa and water is flowing with a speed of 2.0 m/s. The pipe narrows to 2.0 cm. What is the pressure in the narrower region? Treat the water as an ideal incompressible fluid. The density of water is 1000 kg/m3 . (1 kPa = 1000 Pa)
