TīmeklisThe standard configuration for characterizing a speaker is to place the speaker under test in an anechoic chamber, place a microphone 1 meter in front of the speaker and then drive the speaker with a 2.83 Volt signal (1 Watt into 8 Ohms). The equation for the sensitivity of a speaker is expressed as: S = 20 log 10 (P/P ref) Quantities P and P ...

The pan evaporation values are added up every day till it is equal to certain ratio of the amount of water applied as irrigation. The ratio for various crops is determined experimentally by estimating the evapotranspiration by lysimeter studies. scotwood industries traction melt
