a firm is deciding wheter to buy or rent equipment. How many days would they need to use the equipment each year to justify purchasing the equipment? To purchase equipmet/ Buy at $60,000, Operation and maintanence is $120/day, life is 5 yrs and salvage value is $5000. To Rent: is $400/ day, life is 5 yrs. Use a interest rate of 5%. Which alternative would be better if the equipment is operated 25 days per year?
A 32-in.-wide by 0.125-in.-thick by 110-in.-long steel sheet is to be formed into a hollow section by being bent through 360° and having the long edges welded (i.e., butt-welded) together. Assume a cross-sectional medial length of 32 in.
A hot air balloon starting on the ground ascends at a rate of 12 km/hr and is carried by the wind (horizontally) at a rate of 20 kn/h. When the balloon reaches a height of 50 m, a ballast bag is dropped.
Plot the variation with depth (z) of the at-rest lateral earth pressure behind the wall, and determine the magnitude and location of the at-rest lateral earth force per unit length of wall.
Assume the rate constant for BOD decay is 0.2 d^-1, the mean velocity of the stream is 0.5 m s^-1, and the initial concentration is 100 mg L^-1 at x=0. Plot the resulting concentration with downstream distance x in km.
A 40 oF breeze of 10 miles per hour blows over the top of a round open-top water cooling tank which has a bulk temperature of 100 oF. What is the rate of energy in kW that enters into the air
What is the TCE concentration in ppm if the tank is held at (a) 4 degrees C and (b) 35 degrees C (c) What is the TCE concentration in ppm if the tank is filled with hexane instead of water
The channel has side slopes of 4H:1V and a longitudinal slope of 0.5%. Assume a depth of flow of 6-inches. The parking lot slopes at 1% toward the channel from both sides, and the 2-year, 24-hour rainfall is 2in.
for this purpose replace this force by its equivalent of two forces at At Ft parallel and Fn perpendicular to the beam. Determine Ft and Fn.
a temperature probe moves with the velocity 2i+2j-3k through air. the temperature of air changes as T(x,y,z,t)=(2x^2-3y+z^3)cos(at). Find the rate of change of temperature measured by the probe.
The floor area of each floor in these buildings is 400 m^2. The buildings are separated by large lawns so that the (Exposure + Communication) factor = 1.2.
An engineer is to design a channel lined with planed wood to carry 2 m3/s of water on a given slope. The channel cross section can be either a 90 degree triangle or a square. Which would require less wood and by what percentage
A membrane biological treatment plant effluent must be disinfected to what level prior for use as unrestricted recycled water. For a flow of 4 mgd and peak flow of 6 mgd, how many lamps are required
