A 50 hp motor with an efficiency of 0.80 is to be replaced by a newer model motor with an efficiency of 0.90. The motor is expected to operate 3000 hours per year. The cost of electricity in our area is $0.06 per kWhr.
a. What is the expected annual energy savings in kWhrs?
b. What is the expected annual cost savings in dollars?
We're asked to determine the deflection of a beam location for a 2000N load. However the force is directed up the corner NOT centroid.
Assuming that the bomb is perfectly insulated what is the temperature of the air in the bomb at the end of filling process? Assume air is an ideal gas with constant specific heats in a ratio Cp/Cv = γ = 1.4 and constant R= 287 J/kg K.
Finding the volume of hydrogen, A hydrogen filled balloon of the type used in cosmic ray studies is to be expanded to its full size which is a 100-ft diameter sphere, without stress in the wall at an altitude of 150,000 ft.
