The development of this factory resulted in frequent floods in the area, mostly due to the addition of impervious surfaces. The owners of the factory want to make changes to prevent future flooding. Help the owners brainstorm solutions for the flooding problem

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
