Chapter 5, Problem 5.22CU

The larger the specific volume, the greater the work produced (or consumed) by a steady-flow device.

Based on thermodynamics of a process, explain intermediary energy. Mention the three characteristic features of this intermediary energy

A closed system undergoes a thermodynamic cycle with 2 steps: process 1-2 (from state 1 to state 2), process 2-1 (from state 2 to state 1). During process 1-2, the system received energy by heat transfer of 25J. During process 2-1, energy was transferred from the system to its surrounding by heat transfer of 15J. This is a power cycle. True or false?

Energy: 1. What is the Law of Conservation of Energy? 2. What is the Law of Conservation of Matter? 3. Why do organisms need energy?

____________is a form of energy which is contained in (possessed by) a body

Prove that for an isolated system, there is no change in internal energy.

Explain the ENERGY BALANCE FOR CLOSED SYSTEMS.

A claim states that a power cycle has been invented that produces work of 400KJ and requires energy transfer to the system of 300kJ. Such device is possible. O True O False

During a steady flow process, the pressure of the working substance drops from 200 to 20 psia, the speed increases from 300 to 1500ft/s, the internal energy of the open system decreases 25 BTU/lb, and the specific volume increases from 1 to 8 ft3/lb. heat is lost by 10 BTU/lb. what is the kinetic energy in point 1 and 2, and flow work in point 1 and 2?
