A well-insulated heat exchanger is used to heat water (cp = 4.18 KJ/kg*K) from 300 K to 90°C with a mass flow rate of 3 kg/s. Determine the exit temperature of the oil, and the entropy generation of the heat exchanger.
A campfire is a chemical reaction involving wood and oxygen from the air. In light of the law of conservation of mass, explain what happens to the mass of the wood during the reaction.
A 5.50 x 104-kg space probe is traveling at a speed of 15000 m/s through deep space. Retrorockets are fired along the line of motion to reduce the probe's speed. The retrorockets generate a force of 3.00 x 105 N over a distance of 2500 km. What is
Astronaut Alan Shepard took a golf ball to the Moon. He hit what is thought to be the longest golf drive in history. What speed would an astronaut need to give a lunar golf ball in order to put the ball in orbit around the Moon? Do you think it co
The turbine is adiabatic, and kinetic and potential energy changes are negligible. If the isentropic turbine efficiency is 75%, determine the work per unit mass flow in KJ/kg, and plot on an h-s diagram.
Determine if this device is consuming or generating work? How much? Also determine the entropy change for the flowing air and comment on its value and sign.
An X-ray source of unknown wavelength is directed at a carbon sample. An electron is scattered with a speed of 4.5 x 107m/s at an angle of 60o. Determine the wavelength of the X-ray source.
