How do skiers reduce drag?
How do skiers reduce drag? Skiers can reduce drag by performing an effective ‘tuck’. To do a tuck, lower your stance and level your back parallel to the slope. This position means less wind hits your body, and the eggs-with-legs shape lets wind cut around you, reducing drag even further. Why do longer skis go […]
How do you find boiling point with temperature and pressure?
How do you find boiling point with temperature and pressure? If the boiling point values for a specified substance at a specified BP temperature and pressure are given, one can determine the Boiling Point at different vapor pressure values using the Clausis-Clapeyron Equation. The Clausis-Clapeyron Equation is derived from VP2=VP1e−ΔHvRT at two different temperatures. What […]
