Thanks. If I grasp something out of the definition, the candela is 1/683 of a watt through I totally have no idea about the steradian d even less concerning the lumens. 1500 candela is 2.19 watt i.e for 60 watts, i need 41095 candela. Am i correct?

I am working on rendering in Autocad and I have came across light. A point light representing a bulb has intensity measured in candela, default value 1500 Cd. I want to represent a normal bulb of 60 watts used for a room. Is there a way to calculate Candela to Watt? Can anyody help me on this...

I am looking a definition and application of Radii of Gyration. I want to understand this concept by looking at a 50x100 Tube withstanding wind pressure as I have drawn using Autocad. So far I do know that the greater the Radii of Gyration, the greater the rigidity of the section i.e the...

I have just check the excel sheet anew, there is no discrepancy. The wind speed using equation and online converter is 219.4 km/h using a wind density of 1.2923 kg/cu m.

Thank you for your reply. I have a pressure of 2400 Pascal. Reworking your formula from the standpoint of pressure and using a density of 1.2923 (kg/cu m), I am getting as answer: 60 for velocity. (I think it is 60 m/s or 216 km/h). I have used an online converter called Cactus 2000...

Hi, I want to express a wind pressure of 2400 Pascals in terms of km/h (speed) ? The context here is Aluminium Openings having to resist such pressure. Thanks in advance, Regards, Nicolas.
