Written assignment -- turn in to professor...it goes on, suffice it to say that people are teaching with Dune. We shall either shortly inhabit the stars or someone will boil in a homemade LARP stillsuit (see question 8).
Note: It is HIGHLY RECOMMENDED that you paste these questions into Word and type your answers. Also, it is extremely helpful to present the questions in the order listed.
1. There were no camels onDuneArrakis (FT), but we could easily imagine them there. Most mammals die if they lose 10-15% of their body fluid. For camels, this number is nearly 30%. The mass of a camel is around 700 kg and can drink up to 100 liters of water at one time. (This amount would kill any other animal!) Find the percentage of the camel’s mass that is body fluid.
If 100 liters = 30% of the camel's water, what is 100% ?
100 L/x = 30%/100% 100/x = 0.3
x = 100/0.3 x = 333 liters of camel body fluid
Since the density of water is 1.0 kg/L: 333 L x (1000 ml/L) x (1g/ml) x (1kg/1000g)
= 333 L = 333 kg
333 kg water/700 kg total body mass = 47.6% of the camel’s mass is water
2. Jamis’ body produced a little over 33 liters of water. How many pounds did Jamis weigh?
If 60% of the human body mass is water, then 60% of Jamis's body mass X = 33 L. So what is 100% of X?
60%/100% = 33 L/x 0.6 = 33/x x = 33/0.6 x = 55 L
55 L = 55 kg (see #1)
55 kg x (2.2 lbs/kg) = 121 lbs
