1. Design an apparatus to measure the dew point of an air sample based on the cooling of a mirrored surface until it fogs. If possible, build and test this apparatus. (Suggestion: Consider thermoelectric cooling of a polished metal plate.)
2. Design a system to remove the respiration carbon dioxide from inside a spacecraft and replace it with oxygen. Use a living quarters volume of 10.0 m3 with the crew generating a maximum of 2.00 × 10-5 m3 /s of CO2.
Assume the mixture enters your system at 30.0°C and exits it at 20.0°C. Maintain the same oxygen partial pressure in your mixture as that in atmospheric air at 0.1013 MPa and 20.0°C.
A crate with a mass of m is on a ramp that is inclined at an angle of 30degree from the horizontal. A force with a magnitude of F directed parallel to the ramp is used to pull the crate with a constant speed up the ramp a distance of d. What is th..
