PURPOSE: To enable a wind direction and wind velocity measuring instrument to accurately measure the direction and velocity of an air current generated in a closed space even when the air current is very weak and, at the same time, to make the handling and operation of the instrument easier ...

Contrary to dry-arc distance, increasing the leakage distance as a remedial measure becomes less effective under moderate and heavy ice accretion that bridges the inter-shed insulator spacing. However, this measure can be efficient under cold fog conditions, where a thin ice film is formed along ...
when the air pressure drops, bad weather is coming. And when it goes up, good weather is coming. There is other equipment, too. A rain gauge measures the amount of rain that has fallen in a place. And an anemometer is used to measure how fast the wind is blowing. It's really usefu...
measure of how cold the month was. Now if one plots the monthly degree days against heating energy consumption (gas if heating is from gas) one would expect them to rise and fall together. An example for one year of data is shown inFigure 10-26with a trend line added. Now in a ...
