Natural gas is widely used as fuel in the process industries, so the price of natural gas is often an important variable in economic analysis. Develop a 15-year forecast of U.S. natural gas prices. Historic natural gas prices are available at www.eia.doe.gov. The "industrial" price data set is most typical of the contract prices paid by large industrial consumers. Consider any structural changes that may have occurred in the natural gas market when making your forecast.
Temperature variations are small over the shaft cross section. Evaluate the temperature and conduction heat rate at the shaft-pipeline joint (x = 0) and at the shaft-ground interface (x = 1 m)
Consider that you are a senior consulting engineer and that you need to explain the topic in a written report to your customer, who is the managing director of a large company, and a commerce or law graduate.

The composition of a gas derived by the gasification of coal is, volume percentage: carbon dioxide 4, carbon monoxide 16, hydrogen 50, methane 15, ethane 3, benzene 2, balance nitrogen. If the gas is burnt in a furnace with 20% excess air, calcula..
Develop and execute a PS pice program to analyze the circuit shown in Figure P2.5.1 to evaluate the node voltages and the current through each element.
For the design of internal-pressure cylindrical vessels, the API-ASME Code for Unified Pressure Vessels recommends the following equations for determining the minimum wall thickness when extreme operating pressures are not involved:
Develop a two-dimensional addressing system using a 6-to-64 decoder, a 64-word×128- bit matrix, and 16-input multiplexers. How many gates would such a system require?
A mixture containing 98 mol% methanol and 2 mol% of an inert contaminant is available as a feed to a formaldehyde plant. The fresh feed to a process consists of 1000 kmol/h of this mixture along with 200 kmol/h of oxygen. All of the oxygen is consume..
A 100.0-L aliquot (portion) of this solution is diluted to a final volume of 100.0 mL. Calculate the concentration of the final solution in terms of molarity.
what is the Pareto efficient number of streetlights to provide? (HINT: you have to calculate social marginal value and put it equal to marginal cost).
The total brush-contact drop is 2 V, and the core and rotational losses are 380 W. Assume that stray load loss is 1% of output. Compute the efficiency of the motor.
A spherical ball of benzoic acid (diameter = 1.5 cm) is submerged in a pool of still water. The solubility and diffusivity of benzoic acid in water are 0.03 kmol/m3 and 1.25 x 10-9 m2/srespectively.
