Compute the approximate survival time of a human in cold water
ResourceFunction["ColdWaterSurvivalTime"][temp] estimates the survival time in cold water for a temperature temp. | |
ResourceFunction["ColdWaterSurvivalTime"][temp,prop] gives the property prop. |
"SurvivalTime" | time a human can survive in cold water of the specified temperature |
"MetabolicHeat" | heat generated by the body in the cold water |
"CoolingRate" | body's cooling rate |
"Plot" | plot of the curve of survival time versus water temperature |
"PropertyAssociation" | all results as an Association |
"EnergyUnit" | "Calories" | unit of the result heat ("Kilojoules", "Watts", …) |
"TimeUnit" | "Minutes" | unit of time in the results |
Get the survival time in cold water at a specific temperature:
In[1]:= |
Out[1]= |
The function interprets any unit type of degrees for temperature:
In[2]:= |
Out[2]= |
The function used with one argument is similar to the function with two arguments where the second is "SurvivalTime":
In[3]:= |
Out[3]= |
In[4]:= |
Out[4]= |
If a Quantity is not specified, it is interpreted in "DegreesCelsius":
In[5]:= |
Out[5]= |
Obtain the heat generated by the body in water at the specified temperature:
In[6]:= |
Out[6]= |
Obtain the body’s cooling rate for a specific temperature:
In[7]:= |
Out[7]= |
Use "Plot" to obtain the survival time curve (y axis) for different water temperatures (x axis):
In[8]:= |
Out[8]= |
Use "PropertyAssociation" to get all the information simultaneously for a specific temperature. Note that the result is given in the same temperature units as the input:
In[9]:= |
Out[9]= |
Get information using another unit of heat with the option "EnergyUnit":
In[10]:= |
Out[10]= |
Choose another unit of time with the "TimeUnit" option:
In[11]:= |
Out[11]= |
Change both the unit of energy and the time. The plot and the result use the chosen time unit and a given requested energy unit:
In[12]:= |
Out[12]= |
Note that even if the temperature unit is not degrees Celsius, the x axis of the graph remains in that unit:
In[13]:= |
Out[13]= |
If the required property does not contain information about the energy, the "EnergyUnit" option does not influence the output:
In[14]:= |
Out[14]= |
