Water level will increase. There is a linear relationship between pressure and depth. Depth multiplied by specific weight is hydrostatic pressure, so pressure will increase.

I got the logic of no string. The ball sink or float; in both cases weighing machine will read higher weight. With string but ball has lower density then again weighing machine will read more. Finally in the case of ball of higher density with water but with string; string will have some tension...

Weighing machine measures the normal contact force between container and the machine. Now when ball is dipped with string. I got lost in free body diagram.

Suppose a container is full of water is placed over a weighing machine. Now a ball is hanged with massless string but dipped inside the tank and ball is not touching the bottom. What will be the new reading on the weighing machine?

Just see the TS diagram of say taking R134a refrigerant. I am not getting it :( please help

It appears very non intuitive to me seeing TS diagram of vapour compression system; Area under the curve increases. But how seriously how higher evaporator temperature will lead to higher refrigeration effect. Refrigeration effect means lower temperature.

Let me give you the dimensions of the tank 600mmx450mmx300mm it is a model in laboratory. I was doubting about hydraulic diameter concept for the characteristic length of whole box instead of treating as individual walls.

Actually I need to calculate the cooling load of the chilling tank. I calculated cooling load of brine placed inside the box but I also want to calculate the heat leakage from the system and I want to consider the conduction and convection.

Can I consider wooden box having four vertical plates and one horizontal plate at top...

It is a wooden box and also I need to know the method to get there. Analytical or approximate.

I have a cuboid shaped box. It is being used as a chilling tank in my refrigeration system based on Evan Perkins cycle. For heat load calculation I tried to calculate the heat leakage in the sysyem. So I considered conduction and natural convection. I am in preliminary stage, so no use of...

I am getting your point but somehow I am not satisfied, can you please elaborate espicially your density logic.

Yeah in in Pv diagram of water I have series of points on the horizontal line inside the vapor dome.

How? I can have different specific volumes based on different dryness fraction.

Total mass is always nM, now when container is influenced by gravity some molecules will drift downward and localised higher density region is created opposite what we had uniform density region. Now more number of collisions is there in the downward region while less number of collisions in...
