The basic barometer can be used to measure the height of abuilding. If the barometric readings at the top and at the bottomof a building are 28.7 and 29.7 in Hg, respectively, determine the height of the building in feet. Assume an average density of air of 0.0737lbm/ft^3.
A four year financial project has net cash flows of $20,000; $25,000; $30,000; and $50,000 in the next four years. It will cost $75,000 to implement the project. If required rate of return is 20%, conduct a discounted cashflow calculation
An empty air tank has a volume of 0.024 m3. The compressor on the tank is run until the pressure gauge reads about 65 psi (or 22,500 Pa). Assuming the temperature of the tank is 25 C, find the density of the air and the weight of the air in the ta..
If t his house were heated instead by a heat pump that has an average COP of 2.4, determine how much money the homeowner would have saved that month. Assume the price of electric power is $0.085 per kW - hr.
A 1 m diameter unfinished concrete pipe (n = 0.015) has a slope of So = 0.001 and conveys water at Q = 0.5 m3/s. Find the normal depth yo and critical depth yc.
A vertical triangular orifice in the wall of a reservoir has a base 0.9m long,0.6m below its vertex and 1.2 m below the water surface. determine the theoretical discharge?
The stream from a gas well is a mixture containing 50 mol % methane, 10 mol % ethane, 20 mol % propane, and 20 mol % n-butane. This stream is fed into a partial conderser maintained at a pressure of 250 psia
determine the preassure in psi at a depth of 20 ft below the free surface of a body of water and find the absolute pressure when the barometer reads 29.9 inches of mercury.
Estimate teh excess solids production of an extended aeration process treating unsettled wastewater with a BOD of 200 mg/l and suspended solids concentration of 240 mg/l, assuming k=0.35.
Your engineering consulting firm has been asked to determine the specific weight of an unknown material. You decide to use the concept of buoyancy to figure this out. So you weigh the material in both air and water.
How do the concepts of green design, industrial ecology, and sustainable developement differ from past approaches to engineering design Prepare a brief report on this topic using some specific examples for illustration.
A horizontal cylindrical tank 4 ft in diameter and 10 ft long is full of water. Find the work done in pumping the water to a point 4 above the top of the tank.
