AI Thread Summary
Radiographic testing is a critical non-destructive testing method that utilizes various forms of radiation, including X-rays and gamma rays, to inspect materials for defects. The discussion covers the historical context, current practices, and future advancements in radiography, emphasizing the physics behind radiation, including ionization and the inverse square law. Key topics include the interaction of radiation with matter, radiation safety, and the importance of equipment such as X-ray sources and radiographic film. Techniques for imaging, exposure calculations, and quality control are also highlighted, alongside advanced methods like real-time radiography and computed tomography. The thread illustrates the relevance of industrial radiography in non-destructive testing and its growing recognition within the physics community.

I'm surprised to find a thread about industrial radiography on this physics forum! I'm in the industry as well and most people I've spoken to haven't heard of NDT. It's neat to come across information about it on here.
 

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...
