A mixture of 1 mol of H2O, 2 mol of O2, and 5 mol of N2 is heated to 2200 K at a pressure of 5 atm. Assuming the equilibrium mixture consists of H2O, O2, N2, and H2, determine the equilibrium composition at this state. Is it realistic to assume that no OH will be present in the equilibrium mixture?
A dam spillway is to be tested using kinematic similitude (Froude scaling) with a 1:20-scale model. The model flow has an average velocity of 0.7 m/s and a flow rate of 0.06 m3/s.
A power plant operates at steady-state. It receives energy from a hot source (combustion of fuel) at a temperature of 420 oC. The plant discharges this energy to a nearby river that acts as a cold source.
A room 4x5x6 meter is heated by a baseboard resistance heater. We want the heater to raise the room temperature from 7 to 23 deg C in 15 minutes. There are no heat losses from the room, and specific heat may be assumed constant. Power costs 15 cents ..
Determine the excess pressure inside an 0.5-in-diameter soap bubble floating in air, given the surface tension of the soap solution is 0.0035 lb/ft.
A motorcycle starts from rest at time t=0. The force on it from t=0to 30 seconds is F=300-9t. The combined mass of the motorcycle andthe rider is 225 kg. Use the Impulse and Momentum method to find the magnitude of the velocity at t=30 seconds.
A column is packed with sedimentary material with K = 8.2 x 10-6 m/s. The head at the inlet of the column is 1.99 m. The head at the outlet of the column is 1.87 m. The column is 1.25 m long. What is the volumetric flux through the column?
An emission control system for a new car costs $800 and reduces NO_x emissions from 0.4 g/mile to 0.23 g/mile. Assume the car is driven 10000 miles per year, and the life of the emissions control system is 11 years with zero scrap value.
determine the preassure in psi at a depth of 20 ft below the free surface of a body of water and find the absolute pressure when the barometer reads 29.9 inches of mercury.
A block of mass m is attached to two springs as shown. Knowing that in each case the block is pulled through a distance x from it's equilibrium postition and released, determine the maximum speed of the block in the subsequent motion.
A large pipeline with a 1.200 meter inside diameter carries oil similar to SAE 10 at 110 degrees celcius (sg=0.8). Compute the volume flow rate required to produce a Reynolds number of 3.60 x 10 ^4.
Discuss the advantages and disadvantages of using 8-bit and 10-bit resolution for the analog-to-digital converter.
A trapezoidal canal of side slopes 1V : 2H, and having n = 0:017 is to carry a uniform flow of 37 m^3/s on a slope of 0.0005 at a depth of 1.5 m. Calculate the base width of channel
