Define shear stress as it applies to a moving fluid.
Shear stress as it applies to a moving fluid.
Explanation of Solution
Shear pressure is most ordinarily connected to solids. Shear powers acting extraneously to a surface of a strong body cause disfigurement. As opposed to solids that can oppose miss happening, fluids do not have this capacity, and stream under the activity of the power. At the point when the liquid is in movement, shear stresses are created because of the particles in the liquid moving in respect to each other.
For a liquid streaming in a pipe, liquid speed will be zero at the pipe divider. Speed will increase while moving towards the focal point of the pipe. Shear powers are regularly present on the grounds that adjoining layers of the liquid move with various speeds contrast with one another.
By thinking about the speed of this relative movement, shear rate,

- Problem 1.13 The velocity distribution for flow over a flat plate is given by u = y- y in which u is the velocity in metre per second at a distance y metre above the plate. Determine the shear stress at y = 0.15 m. Take dynamic viscosity of fluid as 8.6 poise. %3Darrow_forwardThe figure below represents the working principle of an industrial pressure gauge. The cylinders and tubing are filled with an oil whose density is 0.780 g/cm3. The sections transverse pistons have an area of 40 cm² and 4000 cm² (a) Calculate, in N, the value of the force F to be applied to the smaller piston of the press shown in the figure, required to balance the load F’ of 4400 kgf on the larger plunger.

The barrel of the syringe has a cross-sectional area (2.50x10-5) m2, and the needle has a cross-sectional area (1.00x10 8 ) m². In the absence of a force on the plunger, the pressure everywhere is 1.00 atm. A force F of magnitude 2.00 N acts on the plunger, making medicine squirt horizontally from the needle. Determine the speed of the medicine as it leaves the needles tip.arrow_forward
