For a creeping flow, find the viscosity of liquid. Given: solid sphere, 8.0mm=D, density= 1200 kg/m^3 is released in a liquid with density= 1100 kg/m^3 at a terminal velocity 9.00mm/s

Solutions

Expert Solution

Solution :

For creeping Flow ( Stokes Flow) We have to take equation of Terminal Velocity from literature.

Equation as following:

Where,

Vt = Terminal Velocity

r = Radius of moving Sphere

= Density of Moving Sphere

= Density of liquid

g = gravitational accelaration

= Viscosity of Liquid

Given Data:

Vt = 9 mm/sec = 0.009 m/sec
r = 4 mm = 0.004 m
= 1200 kg/m3
= 1100 kg/m3
g = 9.8 m/sec2

Put All above Values in Equation & Find .

= 0.3871 kg/m.sec

Answer:

Viscosity of Liquid = = 0.3871 kg/m.sec

A solid steel sphere of radius 1.50cm and density of 8045 kg/m³ was launched on a horizontal frictionless surface. The sphere was launched using a spring gun which possessed a spring with a force constant of 35.6 N/m. The spring was compressed 30.0 cm and the sphere was launched. At the end of the frictionless surface (that was 0.955 m above the floor), the sphere rolled (no slipping) up a 25° ramp with height of 1.15m and then launched off...
