The following characteristics of coffee have an adverse effect on the upper GI tract: Coffee Decreases Pressure in the Lower Esophageal Sphincter Coffee has been shown to decrease pressure in the lower esophageal sphincter, contributing to gastroesophageal reflux.
Here is how to properly measure and calculate total square footage of the space. 1  Split the room into separate areas. 2  Measure each area of the room separately (area 1, area 2, area 3). 3  Calculate the square footage of the each space by multiplying length by width. 4  Room: Length (ft) x Width (ft) = Square Footage.
Here's a formula that should correlate well for a one room house where the room is square and has no ceiling fixture. L = 4 x sqrt(A), where L is the total wire length and A is the room area. If A = 100 sq. ft, L = 40' of wire. For A=1000 L = 126' and for 2000 it's 179'. For non-square rooms and multistory houses it gets more complex.
