Question

Convert:

1) 295 K to °C, °F, and R;
2) 100 Btu/ft².s.°F to W/m².K.

Answer 1

295 K is equivalent to 22.2 °C, 71.96 °F, and 531 °R. To convert 100 Btu/ft².s.°F to W/m².K, the result is approximately 567.83 W/m².K.

Step-by-step explanation:

The student asked to convert 295 Kelvin (K) to degrees Celsius (°C), degrees Fahrenheit (°F), and Rankine (R), and to convert 100 Btu/ft².s.°F to Watts per square meter per Kelvin (W/m².K).

Converting 295 K to °C, °F, and R

For Celsius: Use the formula T(°C) = T(K) - 273.15, which gives 22.2°C

For Fahrenheit: Use the formula T(°F) = T(°C) × 9/5 + 32, which gives 71.96°F

For Rankine: Use the formula T(R) = T(K) × 1.8, which gives 531 °R

Converting 100 Btu/ft².s.°F to W/m².K

This conversion involves several constants and requires a two-step conversion process: Convert Btu to Joules and °F to °C, then convert ft² to m². The simplified conversion factor is 1 Btu/ft².s.°F = 5.678263337 W/m².K, hence 100 Btu/ft².s.°F = 567.8263337 W/m².K.
