Is Your Steam Saturated or Superheated?

AI Thread Summary
To determine if steam is saturated or superheated, refer to the phase diagram of water, which requires knowledge of temperature and pressure. When boiling water, steam can appear clear (dry) near the spout and become visible (wet) as it cools and condenses. Dry steam is hazardous due to its latent heat of vaporization, which can cause severe burns upon contact with skin. To test steam, cool it slightly and observe for condensation; if condensation occurs, the steam is saturated. Understanding these properties is crucial for safety and effective steam usage.

hi guys can you tell,

how to know if steam is saturated or superheated?

Look up the phase diagram of water. You need to know the temperature and pressure..

When you boil a kettle the water vapour coming out can be clear (eg dry) near the spout then as it moves away it cools and condenses to visible (wet) steam. Dry steam is very dangerous because it contains the latent heat of vapourisation. When it condenses on skin it delivers a lot of energy.

Cool it a little, and see if you get any condensation.
 

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...
