What is the coefficient of drag for a flow of air (rho = 1.225 kg/m^3), mu = 1.8 times 10^-5 ns/m^2) over a flat plate that is 93-cm long, if v_infinity = 86 m/s? select one: a. 3.38e-3 b. 8.27e-3 c. 5.70e-3 d. 2.19e-3

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.

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false
