Value, measure, or degree; a charge, payment, or price determined through the application of a mathematical formula or based upon a scale or standard.

For example, an interest rate is determined by the ratio between the principal and interest.

Rate is also used synonymously with tax.

If the ventilation rate is reduced the amount introduced indoors is relatively small, leading to low concentrations especially if the pollutants are of high adsorption characteristics (Yanagisawa et al.
Opening windows and doors, operating window or attic fans or running a window air conditioner with the vent control open increases the outdoor ventilation rate.
It continues: "A major concern for the toxicity of DCM is the especially susceptible populations", stressing that children are more vulnerable "due to a potential for higher exposure as they have a higher ventilation rate than adults and the concentration of DCM may be higher at floor level".
This equation can be arranged so that the probability of airborne infection is given by P (infect) = C/S=1-exp(-Iqtp/Q), where C is the number of cases among S persons susceptible to the infection; I is the number of sources of infection; q is the number of "quanta," or units of bacilli necessary to cause infection produced per source per unit of time; t is the time of exposure per unit of time; p is the minute ventilation rate of the exposed susceptible hosts in volume per unit of time; and Q is the volumetric rate of fresh air ventilation that removes the infectious aerosol in volume per unit of time.

Before the energy crisis of the early 1970s, building ventilation rates averaged 15 cubic feet per minute (cfm) of fresh air per occupant, the minimum amount recommended by the American Society of Heating, Refrigerating and AirConditioning Engineers (ASHRAE); areas such as smoking lounges, ASHRAE advised, should have a ventilation rate of 60 cfm.
