A) What are the modern techniques used for enhancing the thermal conductivity of Phase changing materials (PCM) ?
B) what are the negative effects (disadvantages) of using old methods of enhancing thermal conductivity of PCM ? ( construct table )
C) what are the different techniques used for...
Ok what first i did is i have assumed that i have a solid ball having some radius, with the help of that radius i calculated volume , then with density and volume i found mass of that ball
Then i used
Fb = Fg
Till this point the values of these two doesn't comes equal to each other, so now...
Yes sir, i have answered the questions if i assume
inner radius = 0.024m
Outer radius = 0.025m
Then
Fb = Fg
But now we have to find the suspension height of the particle (of assumed radius)
Or let's make it simple i need to find the pressure acting on a suspended particle if these...
"w" is the specific weight of fluid
Where as i have mentioned above i.e at assumed radius Fb = Fg
Where
Fb = density of fluid * volume of fluid displaced * gravitational acceleration
Fg = mass of body * gravitational acceleration
When we attain Fb = Fg body will suspend at any height in...

Where he used this formula to get pressure acting on a immersed surface .
P is pressure acting on a immersed surface.
yes i am using archimedes principle , i have assumed radius as well e.g if we assume that we have wood sphere coated with aluminium and radius of wood particle is 1.9cm and aluminium coating will be taken as hollow sphere having internal radius of 1.9cm and outer radius is 2cm (mean coating...
1. What should be the size of object/Particle (sphere) so that it should remain suspended (neither it should sink nor it should float)? container dimensions 30*25*25, density of fluid 0.9g/cm3 , density of particle 0.86g/cm3 , particle is coated with aluminium having density of 2.07g/cm3.(if...
Hi, i m aqib
i am doing mechanical engineering (final year)
i just joined this forum because i am feeling difficulty in solving Fluid Mechanics Problem And i am hoping i will get help from experts and seniors in solving that
