A gas produced as a by-product from the carbonization of coal has the following composition, mole %: carbon dioxide 4, carbon monoxide 15, hydrogen 50, methane 12, ethane 2, ethylene 4, benzene 2, balance nitrogen. Using the data given in Appendix C (available online at booksite .Elsevier.com/Towler), calculate the gross and net calorific values of the gas. Give your answer in MJ/m3 , at standard temperature and pressure.
Consider a 1-bit version of the digital comparator shown in Figure P6.1.41. Note that the operation of this circuit is such that whichever output is 1 gives the desired magnitude comparison.
A liquid mixture consisting of 100 kmol of 60 mol% benzene, 25 mol% toluene, and 15 mol% o-xylene is flashed at 1 atm and 100°C. (a) Compute the amounts of liquid and vapor products and their composition.
If the transmitted beam is reversed, so that it impinges on the interface from the glass side, calculate what the transmitted angle will be through the tissue. Does this make sense? Explain
What makes mirror reflective?
A storage tank is purged continuously with a stream of nitrogen. The purge stream leaving the tank is saturated with the product stored in the tank.
If a mixture of 5.0 g of hydrogen and 10. g of methane is burned, and the heat released is transferred to 50.0 g of water at 25.0C, what final temperature will be reached by the water?
A three-phase, 60-Hz substation bus supplies two wye-connected loads that are connected in parallel through a three-phase feeder that has a per phase impedance of 0.5 + j2 Ω. Load 1 draws 50 kW at 0.866 lagging PF, and load 2 draws 36 kVA at 0.9 l..
What is the minimum refractory period? If the second pulse is applied before the minimum refractory period, how much larger is the stimulus magnitude that is needed to generate an action potential?
A loaded semi-truck consumes about 10 US gallons of diesel per hour (assuming an average speed of 60 mph) and is driven about 16 hours per day, every day of the year. The density of diesel id 0.85 kg/liter. If 1 barrel of crude oil produces 10..
Calculate the parameters of the equivalent circuit shown in Figure 13.2.5(c).
If this machine is operated from a 440-V dc supply, determine the speed at which this motor will run and the current taken from the supply, assuming no mechanical load, no friction and wind age losses, and that the field current is maintained at 4..
Develop the designed circuit using breadboard in the laboratory. Available thermal sensor can be used in the circuit. Discuss the effect of resistors on calibration of the sensor with specific emphasis on the sensitivity of the instrument.
