A certain process requires 2.8 cfs of water to be delivered at a pressure of 30 psi. This water comes from a large-diameter supply main in which the pressure remains at 60 psi. If the galvanized iron pipe connecting the two locations is 200 ft long and contains six threaded 90o elbows, determine the pipe diameter. Elevation differences are negligible.

Boiling of water in an open container is a constant pressure process. On earth water boils at 100 deg C (atmospheric pressure is 101.3 kPa). If we were to boil 2 kg of water on the surface of Mars, how much energy (Q) do we need to supply? The ΔU for this process is 4750 kJ. Specific volumes of water vapor and liquid are 206.00 and 0.00100 m3/kg, respectively.

At a certain refinery, the refining process requires the production of at least two gallons of gasoline for each gallon of fuel oil. To meet the anticipated demands of winter, at least three million gallons of fuel oil a day will need to be produced. The demand for gasoline, on the other hand, is not more than 6.4 million gallons a day. If gasoline is selling for $1.90 per gallon and fuel oil sells for $1.50/gal, how much of each...

To produce a certain product, there are two competing processes under consideration. Process A requires acquisition of a new machine that is estimated to have an initial cost of $30,000 and a salvage value of $12,000 at the end of its useful life of 6 years. In addition, the process requires a fixed cost of $47,000 per year and a variable cost of $250 per day. Alternatively, Process B requires the use of human labor. The process will need 6...

A random sample of 400 electronic components manufactured by a certain process are tested, and 30 are found to be defective. a) Let p represent the proportion of components manufactured by this process that are defective. Find a 95% confidence interval for p. Round the answers to four decimal places. b) How many components must be sampled so that the 95% confidence interval will specify the proportion defective to within ±0.02? Round up the answer to the nearest integer. c)...

The equilibrium water vapor pressure table gives the partial pressure of water when the gas is 100.% saturated with water vapor. If the gas you collected was actually only 85% saturated with water vapor, calculate the percent error in the number of moles of N2 collected in Part I. mass nano2 = .111g v of wet n2 gas = 37.9 ml partial pressure n2 = .966 atm moles n2 collected = 1.53*10^-3 moles n2 expected = 1.61*10^-3

Imagine you are 2.8 m below the surface of a pool of water looking up toward the surface. How far in front of you would you need to look before you can no longer see through the surface of the water, i.e. the surface starts to appear mirror-like? Assume there is air above the surface. How far from a converging lens with a focal length of 41 cm should an object be to produce a real image that is 2.5...
