Direct Heat Transfer Between a Liquid And a Gas

AI Thread Summary
To calculate the heat transfer rate between a liquid, such as water, and a gas in a chamber, one must consider the temperature difference between the two phases and the contact surface area. The heat transfer can be analyzed using principles of convection and conduction, taking into account the properties of both the liquid and gas. The pressure conditions also play a significant role in determining the heat transfer characteristics. Additional information about the specific temperatures, properties of the gas, and flow conditions may be necessary for precise calculations. Understanding these factors is crucial for accurately determining the heat transfer rate in this scenario.

Hey guys,

I was trying to find the answer to this question but could not seem to find anything. I am trying to figure out how to calculate heat transfer rate between a liquid and a gas. Say the the liquid is water in a chamber (with no heat transfer to the walls). The gas is the residual space above the liquid, meaning that the contact surface is the surface of the water. Given the gas and the liquid are at a certain pressure, but the temperature of the gas and the liquid differ. How can I find the heat transfer rate for this problem? Much thanks for help!

Regards,
Bob

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...

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...

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...
