Water is flowing through a pipe of 5cm diameter under a pressure of 29.43N/cm2 (gauge) with mean velocity of 2m/s.Often, viscosity is referred to as a fluid’s thickness. Find the discharge through the pipe if the velocity of water flowing through the pipe at section 1 is 5m/s. Viscosity is a concept that is used not only in chemistry but also in physics and engineering. The Areas of a pipe at section 1 and 2 are 0.007854m2 and 0.017m2.A property of fluids that allows a water strider to walk on water.When you increase your depth under water, the water pressure on your body.Rank them according to the pressure exerted by the water on the vessel bottoms, least to greatest. The vessels shown above all contain water to the same height.For the same flow rate if the viscosity of a fluid is reduced to half the value of the first fluid, the pressure drop will Two fluids are flowing through two similar pipes of the same diameter.(III) The continuity equation.(IV) Velocity of boundary layer must be zero relative to boundary.(V) Fluid cannot penetrate a boundary. Which of the following must be followed by the flow of a fluid (real or ideal)? (I) Newton's law of viscosity.(II) Newton's second law of motion.The velocity gradient at the point is 0.15 s-1. The shear stress at a point in a liquid is found to be 0.03 N/m2.Which Force is equal to the product of shear stress due to viscosity and surface area of the flow?.
Increasing the temperature decreases the viscosity of a.The value of the viscosity of an ideal fluid is.The correct statement about the viscosity of gases.The most frequently used systems of US customary, or Imperial, units are the British Gravitational (BG) and English Engineering (EE). The kinematic viscosity of water at 20 ☌ is about 1 cSt. Newton's law of viscosity state that shear stress is directly proportional to In fluid dynamics, it is sometimes more appropriate to work in terms of kinematic viscosity.What head (m of water) must the pump generate at its exit (E) to deliver water at a flow rate of 0.001 m³/s? The Fanning friction factor, f is 0.0062. A centrifugal pump is used to pump water through a horizontal distance of 150 m, and then raised to an overhead tank 10 m above.Calculate the discharge through the venturimeter which is used to measure the flow of water if the area at inlet and throat are 706.85 cm2 and 176.7cm2 and difference of pressure head is 252m of water.A stream function is given by Ψ=5x-6y, Calculate the velocity components u and v in units/sec?.It is determined by measuring the time in seconds, required for a fixed volume of fluid to flow a known distance by gravity through a capillary within a calibrated viscometer at a closely controlled. Which one of the following is not a unit of dynamic viscosity? Kinematic viscosity is a measure of a fluid's internal resistance to flow under gravitational forces.Give the dimensions of the following,i) power ii)kinematic viscosity.Which of the following is the dimension of kinematic viscosity?.Specific isobar heat capacity cp steam, specific isochor heat capacity cv steam, adiabatic exponent or isentropic exponent kappa steam, thermic conductivity steam, speed of sound steam.
