   Answer is (C). 7. Steam enters a turbine with a velocity of 40 m/s and an enthalpy of 3433.8 kJ/kg. At the outlet, 2 meters lower than the inlet, the velocity is 162 m/s, and the enthalpy is 2675.5 kJ/kg. A heat loss of 1 kJ/kg is experienced from the turbine casing. The work output per unit mass is closest to. 650 kJ/kg.

   What is the first law of thermodynamics?

   • We will give a more mathematical description of thermodynamical changes later in the course. Law 2 — The first law of Thermodynamics. The internal energy of an isolated system is conserved under any thermodynamical change. This is the macroscopic version of the familiar energy conservation law of physics.

   What is the fundamental law of thermodynamics?

   • This equation is sometimes referred to as the fundamental law of Thermodynamics. For an irreversible process we have dQ < TdS and dW > p dV , but when these infinitesimal heat and work are added together, dU is the same as for a reversible process, leading to an identical infinitesimal change in internal energy.

   What is the zeroth law of thermodynamics?

   • Law 1 — The zeroth law of Thermodynamics. If A, B and C are different thermodynamical systems and A is in thermodynamical equilibrium with B and B is in thermodynamical equilibrium with C, then A is in thermodynamical equilibrium with C. In other words, thermodynamical states exist and thermodynamics is macroscopically complete as a theory.

   Does entropy satisfy the first law of thermodynamics?

   • whole satisfies the first law of thermodynamics, as does each of its processes. The change in internal energy for any cycle is always zero, because the system returns to its initial state, and the area of the enclosed region on the P-V diagram is the net work done in the cycle. Entropy is in some sense a measure of disorder.

   What is the 3rd law of thermodynamics?

   • The third law of thermodynamics states that it is impossible to reach absolute zero, so even an ideal engine can never achieve 100% efficiency. Related End-of-Chapter Exercises: 41 – 43 and 58. If you heat your home using electric heat, 1000 J of electrical energy can be transformed into 1000 J of heat.

   What is the second law of thermodynamics?

   • 5. The second law of Thermodynamics The concept of engine efficiency naturally leads to the second law of thermodynamics. The first law was a generalisation of the principle of energy conservation. It told us which processes were energetically possible, but not every process which is energetically possible does actually occur in nature.

   Chapter 3 The First Law 3.1 Assume you have a metal spring that obeys Hooke’s law: F D c.l l0/, where F is the force exerted on the spring of length l, l0 is the length of the unstressed spring, and c is the spring constant. Find an expression for the work done on the spring when you reversibly compress it from length l0 to a shorter length l0.
