    Pull Temperature
AI Thread Summary
To create a strong pulling force through air temperature differences, a significant temperature gradient is necessary, typically around 20-30 degrees Celsius. The concept of using a glass roof to heat air and create upward air currents is plausible, but the effectiveness depends on the design and size of the opening. Small models may not yield noticeable results due to scale limitations and insufficient temperature differences. To enhance air currents, consider optimizing the size of the opening and the heating source. Overall, the idea is feasible with proper adjustments and understanding of thermodynamics.

Dear physics forum, I'm currently working on a project and wondering what should the air temperature difference be to create a strong pulling force ? I'm working on creating a sustainable house, the concept is to have a enclosed glass roof with an opening that allows the sun to heat the air inside and as the contained air heats up, it will try to escape through the opening hence creating a pulling force, but my question is, is this even plausible? I tried it with a small model and a spotlight, doesn't seem to get any results tho. Need some opinion from you guys.

I am unclear on what you mean, or want, by a strong pulling force?

Do you want something akin to air currents?
 
So sorry that i did not clearly define my question, yes air current.
 

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
