Exam 9: Fluids

A compressible fluid is flowing through a pipe with a constriction.The diameter of the narrow section is 0.8000 the diameter of the wide section.The velocity of the fluid in the narrow section is 1.700 the velocity of the fluid in the wide section.If the density of the compressible fluid is 1.200 kg/m³ in the narrow section,then what is the density of the fluid in the wide section?

A 90.0 kg scuba diver with tanks and equipment is submerged and floating underwater in seawater.The volume of the seawater displaced by the scuba diver with tanks and equipment is

What is the density of a mixture of 85% air (density air 1.20 kg/m³) and 15% water vapor (density of water vapor 0.600 kg/m³)?

What is the buoyant force on a 1.200 kg solid steel ball submerged in water? (density of steel is 7,900 kg/m³)

An incompressible fluid is flowing through a horizontal pipe with a constriction.The velocity of the fluid in the wide section of the pipe is 5.00 m/s and the velocity of the fluid in the narrow section of pipe is 8.00 m/s.The pressure of the fluid in the wide section is 200 kPa.What is the pressure in the narrow section of the pipe? (density of the fluid is 680 kg/m³)

Water is flowing through a pipe with a constriction.The diameter of the narrow section is one-half the diameter of the wide section.If the velocity of the incompressible fluid is 3.20 m/s in the wide section,then what is the velocity of the fluid in the narrow section?

Atmospheric pressure is 1.013 $\times$ 10⁵ N/m².The pressure of the atmosphere in kPa is
