Why in constant pressure process, the change in internal energy becomes '∆U = m × Cv (∆T)'?
Why in constant pressure process, the change in internal energy '∆U = m × Cv (∆T)'?
What does pressure energy mean? Why is the first law of thermodynamics dU=dQ+dW? Which pressure is taken to calculate work, is it gas pressure, external pressure or pressure gradient? What is change in volume with respect to change in pressure at constant tempreture and vice versa for incompressible fluid of given unit mass? What is pressure energy? Is the pressure gradient term in the Navier-Stokes equations the static pressure or the dynamic pressure? Why is the pressure of dark-energy negative? Why is the TS pot pressure always 1.5 times the reactor pressure? What is the difference between pressure and kinetic energy of a fluid? Why is Kinetic energy neglected in steady flow energy equation of a turbine or compressor? Why in adiabatic phases of the carnot cycle, does a gas's volume expand or contract? Is it due to entropy? What is the unit of pressure? Why does the pressure of steam decrease when it passes through an impulse turbine? What is vapour pressure? What is exactly meant by dynamic pressure? What is dynamic pressure? What is the difference between pressure and stress as they have the same units? How can you determine the power dissipation formula? Thermodynamics: TdS=dU+dW..is it applicable only for reversible process and why? Fluid Dynamics: What is static pressure? What is mean effective pressure of an engine? INTERNAL ENERGY=energy stored in the form of heat, ENTHALPY=heat flow, H=U+PV, U=Q+W. Is my way of understanding the above terms correct? Why there is no significance in chnge in entropy and internal energy for solid or liquid? Why is pressure an intensive property? How can partial pressure be calculated? What is the difference between static pressure and hydrostatic pressure? Partial pressures of different substances in atmosphere? What is equilibrium pressure? What is the difference between pressure and flow? What causes the energy losses in a centrifugal pump?
