At steady-state, fuel oil is supplied at 0.01 gal/min to an oil furnace for home heating. (Note: 1 gal = 3.785*10^-3 m^3). The fuel oil density is 870 kg/m^3. Combustion air at 65°F and 1 atm enters the furnace with a volumetric flow rate of 15.2 ft^3/min. Determine the mass flow rate of combustion product gases flowing up the chimney flue. Also, determine the average velocity of the flue gas if the gas temperature is 225°F and the flue diameter is 9 in. Assume that the flue gases behave as an ideal gas with an apparent molecular weight of 29 kg/kmol. Also, assume that the pressure in the flue is essentially 1 atm (absolute).

A double pipe heat exchanger is to be designed to cool 5 gal/min of hot oil from 250°F to 120°F using 10 gal/min of cooling water available at 70°F. The heat exchanger is to consist of sections of 0.75 inch 16 BWG copper tubing inside 1.5 inch 16 BWG tubing; the water flows in the annular space. The shell-side heat transfer coefficient for this system is known to be 737 Btu/hr×ft2×°F. a) Estimate the required length of the countercurrent exchanger,...

In the market for "home heating" consumers typically have several options (e.g., electricity, heating fuel, natural gas, propane, etc.), yet we often think of firms in this industry as behaving like monopolists. Discuss the context in which your electricity provider is a monopolist. Is this characterization universally applicable? Explain your answer. Explain how a profit-maximizing monopolist chooses its level of output and the price of its goods. Even when allowed to collude, firms in an oligopoly may choose to cheat...
