Body language a conversation, 7% of what is communicated is via what is said, 38% is via tone of voice, and the majority, 55%, is via body language. This is also referred to as the ‘7%-38%-55% Rule’, and is often considered in studies of human communications. Whilst there is a wider debate about the percentage share which should be attributed to each of the three contributing factors, it is generally agreed upon that body language plays a fundamental role in determining the attitude a person conveys. A person may alter their body language in order to alter the attitude they convey; this
Well test of volume flowrate e.g., m³/day), formula_3 is the aquifer loss coefficient (which increases with time — as predicted by the Theis solution) and formula_4 is the well loss coefficient (which is constant for a given flow rate). The first term of the equation (formula_5) describes the linear component of the drawdown; i.e., the part in which doubling the pumping rate doubles the drawdown. The second term (formula_6) describes what is often called the 'well losses'; the non-linear component of the drawdown. To quantify this it is necessary to pump the well at several different flow rates (commonly called "steps"). Rorabaugh
