    Drying Evaporation
AI Thread Summary
The discussion focuses on finding the most efficient equation for drying clothes indoors by considering factors like heat, airflow, humidity, and light. The user is exploring various equations, including one proposed by Irving Langmuir, the Penman/Shuttleworth equation, and a mass transfer coefficient equation. They are currently using the equation gh = Θ A (xs - x) from Engineering Toolbox for evaporation calculations. The user seeks confirmation on whether this is the correct approach for optimizing indoor drying efficiency. Understanding the right equation is crucial for effectively managing evaporation rates in indoor environments.

I am trying to find the most efficient way to dry clothes indoors with different evaporation factors
1. Heat/Temperature
2. Airflow
3. Humidity
4. Light (Electromagnetic energy)

But I am not sure what equation to use.
(mass loss rate)/(unit area) = (vapor pressure - ambient partial pressure)*sqrt( (molecular weight)/(2*pi*R*T) by Irving Langmuir?
Penman/Shuttleworth equation?
Mass transfer coefficient?

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Calculate minimum RPM to self-balance a CMG on two legs'
Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...
