Estimate the minimum wind velocity needed to prevent the surface water of a shallow mud puddle from freezing at night if the air temperature is 34 F. Make any necessary assumptions to answer with heat transfer concepts.
Homework Answers
Frost formation on ground is a problem creating scenario .
It happens at night due to the temperature difference at different altitude .
At night the temperature of the air nearer to the ground is lower compared to the air above the ground . It can be said that as altitude increases the temperature of the air increases untill one point .
So when the air temperature is 34 F and assuming a cloudy weather moderate winds of 5mph are sufficient to keep the puddle from freezing .
Cloudy weather helps the ground from not freezing as it retains the temperature and prevents fast heat loss of the ground.
If any questions arises you can ask in the comment section , hoping for your positive feedback .. Thank you !

Snow Making The newer style snowmaking guns use high pressure nozzles used to atomize water into drops and large fans to blow the water droplets out onto the ski hill. See the illustration below The water droplets that are formed are typically on the order of D 2mm and the fan can produce a breeze with a velocity of 10m/s.
