At one spot on venus, the second closest planet to the sun, the surface temperature was 726 k. convert this temperature to °c and °f.

Degrees Celsius

= Degrees Kelvin - 273.15

= 726-273.15

=452.85 °C

Degrees Fahrenheit

= (Degrees C)*9/5 +32

= (452.85)*9/5+32

=815.13+32

=847.13 °F

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
