WebH = E + PV The change in the enthalpy of the system during a chemical reaction is equal to the change in its internal energy plus the change in the product of the pressure times the volume of the system. H = E + ( PV) Let's assume that the reaction is run in a styrofoam cup, as shown in the figure below. Webv = velocity of the system. z = the elevation of the fluid. The fluid entering or leaving a control volume possess an additional energy, the flow work (Pv). Hence, the total energy of a flowing fluid becomes. θ = Pv + u + v 2 /2 + …
WebThe first law of thermodynamics states that the change in internal energy of a closed system equals the net heat transfer into the system minus the net work done by the system. In … WebMay 22, 2024 · From the first law of thermodynamics, the work done by turbine in an isentropic process can be calculated from: WT = h3 – h4s → WTs = cp (T3 – T4s) From Ideal Gas Law we know, that the molar specific heat of a monatomic ideal gas is: Cv = 3/2R = 12.5 J/mol K and Cp = Cv + R = 5/2R = 20.8 J/mol K
WebJul 28, 2015 · From the definition of flow work or flow energy it is equal to 'pv' where 'p' is the net pressure acting on a fluid element and 'v' is the volume of the element. From an elementary dynamic analysis of a fluid particle motion if its moving with constant velocity then the net pressure acting on the particle must be zero i.e, p=0. Then, pv =0. WebWork transfers the energy from the tornado to then couch, giving the cough it's kinetic energy. When an object falls, gravity does work on the object. The work done by gravity converts potential energy to kinetic energy. If we consider the flow of water down a river, it's gravity that gives the water its kinetic energy.
