On a cloudy, windy day in August the temperature above Lake Superior reached 25°C The barometer read 760 mmHg, and a scientist aboard an EPA research vessel measured an oxygen concentration (partial pressure) of 0.18. If there is no water vapor in the air, the oxygen partial pressure would have been 0.2. Assuming that nitrogen, oxygen, and water vapor are the only important contributors to the gas pressure, calculate the equilib-rium constant at 25°C for the reaction:
Using the Internet or any other available sources, explain in your own words why the internal energy of an ideal gas can be regarded as function of temperature only.
Find the Total bulb power in W Total bulb power lost as heat in W Total bulb power lost as heat in joules/second Total bulb power lost as heat in joules Garage air bolume in m^3 garage air mass in kg temperature change in K?
It the mean annual runoff of a drainage basin of 10000 km^2 is 140 m^3/s, and the average annual precipitation is 105 cm, estimate the ET losses for the area in 1 year. What are your assumptions? How reliable do you think this estimate is?
A piston-cylinder device contains helium gas initially at 150 kPa, 20 degrees C, and 0.5 m^3. The helium is now compressed in a polytropic process (PV^n = constant) to 400 kPa and 140 degrees C. Determine the heat loss or gain during this process.
A radiant heating lamp powered by electricity has a surface temperature of 1000 K emitting 500 W. The radiation is absorbed by surfaces at the ambient temperature of 18?C. Find the total entropy generation and specify where it is made, including h..
Use the moment-area method to find the maximum deflection at the middle of the beam. Assume that EI is constant, and neglect the weight of the beam.
differential leveling between benchmarks A,B,C,D, and A gives elevation differences(m) of -15.632, 32.458, 38.214, and -55.025, and distances(km) of 4,6,5, and 3 respectively.
determine the composition of the vapor phase of this mixture. Saturation pressure of NH3 at 25°C is 1003.5 kPa.
A CMFR is to be designed to remove contaminant A from water with a steady-state efficiency of 95 percent. The decay reaction is zeroth order, with a rate constant of 0.1M/h. The inlet concentration of A is 0.5 M.
You are asked to design a horizontal curve for a two-lane road. The road has 12-ft. lanes. Due to expansive excavation, it is determined that a maximum of 34 ft. can be cleared from the road's centerline toward the inside
The curve is to be redesigned for a 70 mph design speed in the year of 2025. Vehicle braking technology has advanced so that the recommended design deceleration rate is 25% greater that the 2011 value used to develop
Calculate the prismoidal correction and compare the prismoidal volume to the corrected end area volume. Station Left Center Right Area (sq. ft.) 1+00 C7.0/ C8.2/ C8.5/ 256.90 31.3 0.0 24.5 1+50 C5.3/ C5.0/ C3.5/ 207.62 29.5 0.0 21.8 2+00
