If there are 6500 degree-days in this area, and the price of fuel is $10 per million Btu, then find the heating cost per square foot per heating season for the un-insulated floor. (ans: $0.68/ft2) If 6-in fiberglass costs $0.40 per square foot, what will be the payback time (as a result of energy savings) on this installation? (ans: 0.7 seasons)
The walls are 10 in. thick with an allowable compressive stress of 300 psi (pounds per square inch). A 3 ft wide vertical strip of wall currently supports both a roof load of 1.5 kips and 11 floor loads of 2.0 kips per floor. Each story is 12 ft tall from floor to floor. The density of the masonry wall is 130 pcf (pounds per cubic foot). What is the maximum total force support by a 3ft wall segment for...
the beam is loaded uniformly from the floor with a live load of
80 pounds per square foot (psf) and a dead load in addition to the
beam self-weight of 60 psf. the beam will have full lateral support
provided by the floor deck, and a compact section will be selected.
Use A992 steel. Design a W-shape floor beam for the intermediate
beam marked A on the floor plan shown below.
a) Use LRFD.
b) Use ASD.
Is loaded uniformly...
QUESTION 8 A pump test was conducted with a well drilled into a 12' thick confined aquifer. The pump produced a steady flow rate of 205 gallons per minute and the two observation wells that are located 75 feet and 150 feet from the center of the well had water levels that were 16 feet and 20 feet above the bottom of the confined aquifer. Calculate the coefficient of permeability of the aquifer's soil. 0.203 feet per second 0.00105 feet per second 0.00203 feet...
An indirect lighting system is used to light a square room with a floor area of 400 ft2 . The luminaires in the room uniformly light the ceiling, which is 20 ft high. The walls and floor of the room are very dark and can be assumed to have a reflectance of zero. The ceiling has a reflectance of 0.8. How many lumens must be produced by the luminaires to provide 10 fc on the floor of the room?
4a. The floor deck of a building consists of simple span concrete "T-sections". The reinforced concrete weighs 150 #ft. What is the weight of the an individual T member, in pounds per lineal foot (#) ? 40 4b. What is the average weight of the floor system in pounds per square foot?
If a person who weighs 722.0 N were standing on one foot, and the resulting pressure on the ground were 6.4 psi (pounds per square inch), what is the surface area of the foot on which they're standing? Give your answer in cm Hint: In order to make the unit conversions, you will have to use the fact that: 1N 0.2248 lb and 1 in 2.540 cm
Tire pressure gauges are often calibrated in pounds per square inch. An automobile tire is inflated to a pressure of 30.9 psi. Express this pressure in atmospheres and in millimeters Hg. Hint: 1 atm = 760 mmHg = 14.7 psi Pressure = atm Pressure = mmHg
The pressure in the Mariana Trench is greater than 16000 pounds per square inch. Convert this pressure to atmospheres. [1 atm = 14.7 psi]
1.A double-action rotary cylinder has a vane radius of 11/2 inches and a vane area of 2 square inches. If the input fluid pressure is 1,250 psi and the friction loss is 25 pounds, what will be the torque delivered to the output shaft?
