Consider a home heating system consisting of a natural gas-flied furnace and a thermostat. In this case the process consists of the interior space to be heated. The thermostat contains both the measuring element and the controller. The furnace is either on (heating) or off. Draw a schematic diagram for this control system. On your diagram, identify the controlled variables, manipulated variables, and disturbance variables. Be suit to include several possible sources of disturbances that can affect room temperature.
1. What is the principle of Lime Soda process? Give their functions with chemical reactions. 2. Write notes on Reserve osmosis and Ultra filtration.
Plot of the Fermi distribution function at two different temperatures. Calculate the Fermi timction at 6.5 eV if EF=6 .25 eV and T=300 K. Repeat for T=950 K assuming that the Fermi energy does not change. Plot the energy dependence of the ele..
You are the project manager of a team that has been asked to complete the design of a chemical plant up to the stage of design selection. You have three engineers available (plus yourself) and the work must be completed in ten weeks. Develop a pro..
Estimate the fugacity of cyclopentane at 110 C and 275 bar. At 110 C the vapor pressure of cyclopentane is 5.267 bar. [10.8bar]
The system works reasonably well, all things considered, except that Old Fred has a heavy hand and on the average breaks 30% of the 120 eggs that pass by him each minute. At the same time, a check of the "X-large" stream reveals a flow rate of 70..
A sinusoidal signal, with amplitude of 3.25 volts, is applied to a uniform quantizer of the mid-tread type whose output takes on the values 0, ±1, ±2, ±3 volts. Sketch the waveform of the resulting quantizer output for one complete cycle of the in..
Grams of tin and lead, An alloy is 7 parts tin and 3 parts lead. How many grams of each are in 40g of the alloy? Let x= the number of grams of tin in the 40g of the alloy.
Assuming that there are no other significant side reactions, calculate masses of alcohol and ether produced, per 1000 kg of allyl chloride fed to the reactor.
A living plant contains approximately the same fraction of carbon- 14 as in atmospheric carbon dioxide. Assuming that the observed rate of decay of carbon-14 from a living plant is 13.6 counts per minute per gram of carbon
If a saturated solution of NaHCO3 at 60°C is cooled and comes to equilibrium at 30°C, what percentage of the dissolved salt crystallizes?
Explain Non-adiabatic operations of flow reactors. 15In non-adiabatic operations, heat interchange with the surroundings will beaccounted. The conversion can be defined as the ratio of the net heat still needed after heattransfer to raise the feed..
