How hard design rain falls on a roof gutter in Singapore and Malaysia

The water a roof gutter must carry is the design rainfall intensity multiplied by the roof's catchment area, and codes in England, the US, Australia, Singapore and Malaysia assume very different intensities. On our reading of PUB's rainfall chart, a 100 m² roof at a 30° pitch sends about 7.7 litres a second into its gutter in Singapore's ten-year, five-minute rain.

Neapolitan pizza dough in baker's percentages, from the AVPN and EU rules

Neapolitan pizza dough has two written specifications, the AVPN's and the EU's, and both measure every ingredient against one litre of water. Converted to baker's percentages, the AVPN's 2024 table gives 55.6–62.5% hydration, while the EU text's flour total can be read more than one way.

How the ideal body weight formulas compare from short heights to tall

Four published ideal body weight formulas turn height and sex into one weight, and they were written as drug-dosing and diet references rather than personal targets. For men they come within 1.2 kg of each other at 168 cm and end almost 14 kg apart at 195 cm.

Field-test formulas for VO2 max put the same run at very different values

Field tests estimate VO2 max, the most oxygen the body can use per minute for each kilogram of body weight, from a timed run. Three common formulas put the same 2.4 km run in 12 minutes between 36.3 and 43.5 mL/kg/min, because each turns speed into oxygen in a different way.

Cake tin size charts hold up on area swaps and vary on cups

Scaling a recipe to another cake tin by base area keeps the batter as deep as the recipe intended, while the tin's capacity decides whether it fits. We checked published round-to-square swaps and cups-per-tin charts against geometry and against each other.

Equations estimating a one-repetition maximum match on heavy sets and diverge as reps climb

A one-rep max is the heaviest weight a person can lift once, and published equations estimate it from a lighter set taken to failure. Seven of them give close answers up to ten reps and spread far apart by fifteen. A 2008 study found that most gave no evidence of how they were developed.
