These are equations to calculate reference values for pulmonary function testing. The parameters are for instance TLC (Total lung capacity), VC (vital capacity), FRC (functionnal residual capacity) etc...
NHANES stands for National Health and Nutrition Examination Survey. They are a research based organisation that assesses the health and nutrition of children and adults in the United States.
Based on the NHANES III survey, the 50th percentile height for white males aged 12 is 60.5 inches, or 5'0.5". So you would be about average.

Sarcoidosis of the lungs can be divided into four stages. Stage 0 - No intrathoracic involvement. Stage I - Bilateral hilar adenopathy. Stage II - Pulmonary parenchyma involved. Stage III - Pulmonary infiltrates with fibrosis. Stage 4 is end-stage lung disease with pulmonary fibrosis and honeycombing. Hopefully steroids will stop it at this stage.

The formula for iron(III) chloride is FeCl3. Equations are only for chemical reactions and they show what reactant(s) form what product(s).
Depends on what "school age" is. Here are the average charts by height and weight for children of different ages: For boys: http://www.cdc.gov/nchs/data/nhanes/growthcharts/set1clinical/cj41l021.pdf For girls: http://www.cdc.gov/nchs/data/nhanes/growthcharts/set1clinical/cj41l022.pdf
