Compute the energy consumption in units of joules per year, gigawatts (GW), and watts per person as (a) fuel, (b) food, and (c) solar radiation for a country of population density 20 person/km2, an area of 1 million km2, and a fuel energy consumption rate of 250 GJ per person per year. Solar radiation reaching the ground is approximately 150 W/m2. The average person consumes food containing 2000 “calories” per day (1 calorie = 4182 J).
Because of its metabolic processes, your body continually emits thermal energy. Suppose that the air in your bedroom absorbs all of this thermal energy during the time you sleep at night (8.0 hours). Assume your metabolic rate to be P = 80 J/s.
A 53−kg person drinks5.4×102g of milk, which has a caloric value of approximately 3.0 kJ/g.If only 17 percent of the energy in milk is converted to mechanical work, how high (in meters) can the person climb based on this energy intake? Enter your answer in scientific notation. Hint: The work done in ascending is given by mgh, where m is the mass (in kg), g is the gravitational acceleration(9.8 m/s2), and h is the height (in meters).
If it takes exactly 4 min. to completely melt a 2.0 kg block of ice at 0.0° C, how much power is needed? (For water Lf = 334 kJ/kg and Lv = 2257 kJ/kg.)
This is a calculation only. Energy2d isn’t able to do phase changes as far as I’ve learned. There was a different simulation for this but it is not currently free. You combine 50g of ice at -10oC with 150g of liquid water at 75oC. After a few minutes, you measure the final equilibrium temperature of all of the H2O to be 35.1 oC. Use this information to “experimentally” determine the heat of transformation of water, Lfusion. cwater=4190 J/kgK, cice=2090 J/kgK Show all of your work and compare to the accepted value Lfusion=3.33x105 J/kg.
