Determine the probable production in cubic yard bank measure (bcy) for a 2-cy dragline when excavating and casting good common earth.
The average depth of the excavation is 12 ft, and the average angle of swing will be 1200. The efficiency factor will be a 45-min hour.
a 2.0 cubic meter rigid tank contains a water-vapor mixture at 100 kpa. heat is transfered until the pressure reaches
Piping used in oil refineries usually experiences high pressures and temperatures for extended periods of time, which as you all now know, leads to creep. In this problem, we are going to try and predict the stress-rupture time of a S-590 alloy steel..
the concrete slab of the basement is 11 m long 8 m wide and 0.20 m thick. during the winter temperatures are nominally
When a compressed gas storage tank fails, the resultant explosion occurs so rapidly that the gas cloud can be considered adiabatic and assumed to not mix appreciably with the surrounding atmosphere.
The top of the burner is exposed to room conditions (Tsur,t = Too,t = 20°C, ht = 40 W/m2 · K), while the bottom of the burner is exposed to combus to ensure adequate airflow passage through the array. Recommend a design that enhances chip cooling.
in a close stationary system 2 kg of argon is heated from 20 degree c to 120 degree c. determine the amount of heat
a medical warmer operates using a heat pump. saturated r-12 enters the compressor at a temperture of -10 c and exits as
derive the equation of motion of the simple pendulum consisting of a point mass m attached to a rigid wall by a string
14. For each of the following F values, indicate whether the F is statistically significant at the specified alpha level:a. F = 4.80, df = 4, 40 α = 0.01b. F = 5.02, df = 3, 60, α = 0.001
An ideal gas is confined to one side of a rigid, insulated container divided into equal volumes by a partition. The other side is initially evacuated. The following data are known for initial state of the gas: p1 = 300 kPa, T1 = 380K and V1 = 0.025 m..
what are the commpressive stresses induced by thermal expansion in a cs pipe lined with a zirconium tube that is
For a material with a tensile yield strength Y, determine the ratio of the mean stress o m = to Y at the point of yielding in a
