Question: The science of thermodynamics deals with the amount of heat transfer as a system undergoes a process from one equilibrium state to another and makes no reference to how long the process will take. But in engineering, we are often interested in the rate of heat transfer. In order to determine the rate of heat transfer, one must know the mechanisms/mode of heat transfer. a) State three (3) modes of heat transfer. b) List one example for each type of heat transfer stated in (a). -Free Course Hero Question Answer.

Question: A chemical inhibitor must be added to the water in a boiler to avoid corrosion and scale. The inhibitor concentration must be maintained between 3 and 30 ppm. The boiler system always contains 100,000 kg of water and the blowdown (purge) rate is 15,000 kg/hr. The makeup water contains no inhibitor. An initial 2.8 kg of inhibitor is added to the water and thereafter 2.1 kg is added periodically. What is the maximum time interval until the first edition of the inhibitor? -Free Course Hero Question Answer.

Question: A tracking radar lies in the vertical plane of the path of a rocket that is coasting in unpowered flight above the atmosphere. For the instant when θ=30°, the tracking data give r=25(104) ft, r=4000 ft/sec, and θ=0.80 deg/sec. The acceleration of the rocket is due only to gravitational attraction and for its particular altitude is 31.4 ft/sec2 vertically down. For these conditions determine the velocity v of the rocket and the values of r” and θ”. -Free Course Hero Question Answer.
