the instrument used to measure a change in temperature . Bars AB and CD are made of A-36 steel and 2014-T6 aluminum alloy,respectively. When the temperature is at 75degreeF, ACE is in the horizontal position. Determine the vertical displacement of the pointer at E when the temperature rises to 150degreeF.
Using the USLE, estimate the annual erosion from a 100 ha. forested watershed assuming the following: R =112 tonnes/ha/year. The forest is in fair condition with 40% cover; Average slope is 3%; The soils are clay loam in hydrologic group C.
Air enters an adiabatic nozzle steadily at 300 kPa, 200 o C, and 30 m/s and leaves at 100 kPa and 180 m/s. The inlet area of the nozzle is 80 cm 2 . Determine (a) the mass flow raw through the nozzle, (b) the exit temperature of the air, and (c) the ..
What are 3 of the equivalent fixed-point problems for f(x) = x2 - x -2=0?
a new sports car has a drag coefficient of 0.30 and a frontal area of 21 ft^2, and is traveling at 119 mi/h. how much power is required to overcome aerodynamic drag if p = 0.002378 slugs/ft^3
A circular concrete pipe (n = 0.012) carries a discharge of 450 cfs with a slope of 0.008 and is designed to run no more than 60% full (by depth). What diameter pipe would you recommend
With all the developments and improvements to the GNSS system over the years, what is one important facet of the system that has not improved
helium gas contains trace amounts of methane. Consider a helium balloon pressurized to 5 psi. If methane molar mixing ratio is 800 ppmv, what is the pressure of methane in the balloon
What are Engineering Societies based upon the research? List at least 10 discipline specific engineering societies along with their website addresses.
The aerodynamic drag of a new sports car is to be predicted at a speed of 50mph at an air temperature of 25 degrees Celcius. Automotive engineers build a one-fifth scale model of the car to test in a wind tunnel.
The volume of water in a reservoir is often expressed using the unit of acre-foot. A volume of 1 acre-foot is the amount of water covering an area of 1 acre to a depth of 1 foot. Lake Mead is the largest man-made lake in the United States.
The U.S. Department of Energy (DOE) constructed a Darrieus vertical-axis wind turbine in Sandia, New Mexico. The machine is 60.0-ft tall and 30.0-ft in diameter, and swept an area of 1200 ft 2.
a saturated 100 cm^3 clay sample has a natural water content of 30 percent. it is found that the shrinkage limit occurs when the water content is 19 percent. if the specific gravity of soil solids is 2.70
