A string will break if the tension force is greater than 23N what is the minimum time required to pull a 5.0kg mass a distance of 12m (by using the string). Assume the mass started from rest and the coefficient of kinetic friction is 0.11.

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
