Oil flows through the pipes shown in the figure. The oil’s speed through the lower and upper pipes are v1= 2.5 m/s and v2=5.4 m/s respectively. Take the density of oil to be 900 kg/m3.What does the top pressure gauge read? Express your answer in the unit of kPa.

Water of density 1000 kg/m3 flows through a tube as shown in figure1a below.At section 1 the pressure is 200 kN/m2, the velocity is 5 m/s and the pipe diameter is0.12m. The pipe diameter at section 2 is 0.065m.Calculate: i) the velocity and pressure at section 2

An incompressible fluid is flowing through a vertical pipe with a constriction. The wide section is 2.00 cm in diameter and is at the top of the pipe. The pressure of the fluid in the wide section at the top is 200 kPa. The velocity of the fluid in the wide section is 4.00 m/s. The narrow section is located 4.00 m below the wide section. What is the diameter of the narrow section , if the pressure of the fluid in the narrow section is equal to the pressure in the wide section? (density of the fluid is 680 kg/m3)

Oil, of density 889 kg/m3 and kinematic viscosity 5.68 x 10-5 m2/s, flows through a pipe 6 cm internal diameter at a mass flow rate of 83.2 kg/s.Determine the volumetric flow rate (m3/s).

The water pressure in the mains of a city at a particular location is 269 kPa gage. Determine the fluid column height in "meter unit" corresponding to the given gage pressure.  The density of water is taken to be ρ = 1000 kg/m3.

An incompressible fluid is flowing through a pipe with a constriction. The pipe is on an incline with an angle of 30.0 degrees. The narrow section is 15.0 m from the wide section and the narrow section is lower than the wide section. The velocity of the fluid in the wide section of the pipe is 4.00 m/s and the velocity of the fluid in the narrow section of pipe is 9.00 m/s. The pressure of the fluid in the wide section is 250 kPa. What is the pressure in the narrow section of the pipe? (density of the fluid is 1,000 kg/m3)
