For a 10 ft long A36 solid steel shaft with diameter equaling 4" undergoing a torque of 100,000 ft lb, what is the angle of twist? The Modulus of Rigidity/Shear Modulus of A36 steel is 11x10 psi.

a. 2 33 x 10-4 rad

b. 4.66 x 104 rad

c. 0435 rad

d. 0.522 rad

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false
