Evaporation This is the direct loss of water moisture from the surface of a body of water, the soil and interception storage (on top of leaves) to the atmosphere. Evaporation rates increase when the weather is warmer, windier and dryer. Alternative factors also influence evaporation rates:
Irrigation Water Guidelines - Noble
www.noble.orgWater pH – a measurement which determines the level of acidity or alkalinity of the water. Most water samples have a pH greater than 7.0. Acidic water (<6) could cause corrosion of metal parts in irrigation equipment. Total Dissolved Solids (TDS) – related to the amount of dissolved salts in the water. Higher
Liquid level Measurement - Viatran
www.viatran.comLet’s assume you want to measure the liquid level in a vertical tank 20 feet high. A full tank would exert a maximum hydrostatic head pressure of 20 feet of water column. (Assuming this is water at 4° C.) Since one foot of water column is equivalent to 0.43356 PSI, the maximum
