The conveyor dumps 500-kg of coal per second into the waiting truck. Determine the power consumed by the conveyor motor if its efficiency is 70 percent.
It is subjected to concentrated loads of 20,000 lb at each quarter point and an axial tensile load of 50,000 lb. Calculate the maximum combined tensile and compressive stresses.
2000 kgh of milk is sterilized in a steam infusion sterilizer steam and milk directly contact. the milk is heated to
A fire truck draws water from an open constant-level reservoir through a hose of 0.2 ft2 cross section. The water is discharged from the pump through another 0.2 ft2 hose to a surge tank pressurized to 120 psig with air at the top. The pump adds 970 ..
Evaluate the energy loss is L by recording α and β without any sample - Plot the mass difference Δmversus time for the steel sample exposed to high temperature - Describe the kinetic of oxidation from the curve
steam enters a nozzle with a low velocity at 300f and 30 psi and leaves as saturated vapor at 10 psi. there is heat
The load on the part during service may be as much as 75,000 N. The part is expected to remain below 100°C during service. Design a material and its treatment that will perform satisfactorily in this application.
Calculate the surface temperature of the metal and estimate the uncertainty.
Create an appropriate query to find the titles of all works in the collection and the corresponding composer names. Return the data as a pivot table. Then use the pivot table to find all of the works by Beethoven, Ludwig van. (The database stores ..
A converging nozzle with an exit diameter of 6 cm is attached to a reservoir maintained at 30-C and 150 kPa absolute. Determine the mass ?ux of air ?owing through the nozzle if the receiver exits to the atmosphere.
The saturation pressure at 593 K is 133 bar. Determine the size of the embryo bubble assuming that the surface tension σ?=?10.5 ×?10-6 kN m and the liquid molar volume to be 0.018 m3 kmole-1 .
At the end of the isothermalexpansion, the pressure is 600 kPa and the volume is 0.4 m3. Assuming the ideal gas model for air, determine the thermal efficiency.
