Percent transmittance is the percent of light that passes through an object. If 780 watts per square meter ((W)/(m^(2))) of light strike the roof of a greenhouse, and the roof has an 85% transmittance, how many (W)/(m^(2)) of light pass through the roof?

Identify values: Identify the given values. We have: The amount of light striking the roof: 780 W/m^2 The percent transmittance of the roof: 85%Convert to decimal: Convert the percent transmittance to a decimal. To convert a percentage to a decimal, divide by 100. 85% = 85/100 = 0.85Calculate light passing through: Calculate the amount of light that passes through the roof. Multiply the amount of light striking the roof by the decimal transmittance. 780 W/m^2 * 0.85 = 663 W/m^2

(W)/(m^(2)) of light pass through the roof?

Percent transmittance is the percent of light that passes through an object. If $780$ watts per square meter $\left(\frac{\mathrm{W}}{\mathrm{m}^{2}}\right)$ of light strike the roof of a greenhouse, and the roof has an $85 \%$ transmittance, how many $\frac{\mathrm{W}}{\mathrm{m}^{2}}$ of light pass through the roof?

Full solution

Q. Percent transmittance is the percent of light that passes through an object. If

780

watts per square meter

\left(\frac{\mathrm{W}}{\mathrm{m}^{2}}\right)

of light strike the roof of a greenhouse, and the roof has an

85 \%

transmittance, how many

\frac{\mathrm{W}}{\mathrm{m}^{2}}

of light pass through the roof?

Identify values: Identify the given values. $\newline$ We have: $\newline$ The amount of light striking the roof: $780 \, \text{W/m}^2$ $\newline$ The percent transmittance of the roof: $85\%$
Convert to decimal: Convert the percent transmittance to a decimal. $\newline$ To convert a percentage to a decimal, divide by $100$ . $\newline$ $85\% = \frac{85}{100} = 0.85$
Calculate light passing through: Calculate the amount of light that passes through the roof. Multiply the amount of light striking the roof by the decimal transmittance. $780 \, \text{W/m}^2 \times 0.85 = 663 \, \text{W/m}^2$
