A 10-year, 12%, $1,000 bond that pays dividends quarterly can be purchased for $900. If the bond is purchased and pays as scheduled, calculate the nominal and the effective rate of return that the purchaser receives.
Compare the stoichiometric air/fule ratios (AFR) for complete combustion of Benzene (C6 H6), Octane (C8 H8), and Ethanol (C2 H5 OH) in air (O2 + 3.76 N2). The only products should be CO2, H2O and N2.
Use the Bernoulli equation to describe how this manometer can be used to measure the flow rate through the meter.
The following boundary conditions apply at x=0, ca = Keqcao and T=To and at x=L, (dco/dx)=0 and (dT/dx)=0. Determine the concentration and temperature profiles for this system.
A geothermal power uses hot water (185oF) as a heat source and the cold water from a close by lake (60oF) as a heat sink. The basic operating system is a close loop ammonia efficiency of the cycle that powers turbine-driven electric generator (100..
Assume frictionless flow in a long, horizontal, conical pipe. The diameter is 12 inches at one end and 6 inches at the other. The pressure head at the smaller end is 16 feet of water.
A piston-cylinder device contains 0.2kg of water initially at 800 kPa and 0.06m^3. Now 200 kJ of heat is transferred to the water while its pressure is held constant. Determine the final temperature of the water.
A particle which moves in two-dimensional motion has coordinates given in inches by x=t^2-4t+20 and y=3sin2t, where the time t is in seconds. Determine the magnitudes of the velocity v and the acceleration a and the angle between these two vectors..
A study of the traffic using a tunnel showed that the following speed-concentration relationship applies. Find the capacity of the tunnel, the values of speed and oncentration at capacity, and the jam concentration.
Given that the moduli of electricity of this material are respectively 69GPa and 393 GPa plot modulus of elasticity versus the volum percent of Al2O3 in Al from 0 to 100 vol % using both upper and lower bound expressions
If the pH of a natural water is 7.8, and the alkalinity was measured to be 125 meq/L, determine the following: - Alkalinity as mg/L CaCo3 - Approximate the total carbonate concentration (Ct), in moles per liter.
The wastewater treatment plant for Pine City discharges 1 × 105 m3/day of treated waste to the Pine River. Immediately upstream of the treatment plant, the Pine River has an ultimate CBOD of 2 mg/L and a flow of 9 × 105 m3/day.
