According to the U.S. Geological survey, the volume of water in oceans, seas, and bays is 1.41 ✕ 1018 m3. The average concentration of naturally occurring uranium in seawater is 3.15 ✕ 10−6 kg/m3. If 0.670% of naturally occurring uranium is the fissionable isotope U-235 and each fission reaction yields 200 MeV, estimate the amount of time the uranium in the seawater on the planet could meet the planet's energy needs at an average usage of 1.94 ✕ 1013 J/s.
During a mountain climbing trip it is observed that the water used to cook a meal boils at 93 °C rather than the standard 100 °C at sea level. At what altitude are the climbers preparing their meal? (See Physical Properties of Water (SI Units) and Properties of the U.S. Standard Atmosphere (SI Units) for data needed to solve this problem.) Wiley saids the answer is 2059.7m. I'd appreciate it if somebody would work it out for me
Exhaust gas leaves the exhaust pipe of a motor car with a pressure of 1.2bar and a temperature of 400 degree C. If the exhaust gas specific was 1.6653 m^3per kg, determine the identity of the exhaust gas.
The thermal conductivity of a fluid is 0.09 BTU/ft-h-F having a kinematic viscosity of 0.0215 ft2/h. If the density and specific heat at constant pressure are 53 lbm/ft3 and 0.43 BTU/lb-F, respectively, determine the Prandtl number. Correct Answer: 5.44 ± 0.1
In the United States, electricity is sold using the SI units of kilowatt (kW) or megawatt (MW), and fuel for power generation stations is generally purchased using English units, e.g., British thermal unit (Btu), gallon (gal), and ton. An industrial power plant has an average annual load of 100 MW (electrical). If the overall thermal efficiency is 33% (based on HHV), what is the annual cost of fuel if the plant is fired with (a) natural gas, (b) No. 2 fuel oil, and (c) bituminous coal? Use the data from Tables 2.2, 2.7, and 2.13. Assume the cost of natural gas is $5/million Btu, the cost of No. 2 fuel oil is $3/gal, and the cost of bituminous coal is $60/ton (1 ton = 2000 lbm)

The digital thermometers that we use in the lab today are similar to the ones that we use in our homes, but several years ago scientists used to use glass thermometers that contained a thin column of mercury to measure temperature. Why do you think we no longer use the mercury thermometers in the lab?
