1. The problem statement, all variables and given/known data 2-3-15 2. Relevant equations P = power. W = work. U = internal energy. S = entropy. t = time. Q = heat. T = temperature. F = force. d = distance. P = ΔW/Δt= ΔU/Δt ΔS = ΔQ/T dm/dt = ρ⋅dV/dt W = F ⋅ d ΔU = Q - W Where m is mass, V is volume, and ρ is the density of the fluid. Water ρ = 1000 kg/m3 3. The attempt at a solution Since Uint = 4.2T Uin = (4.2)(300K) = 1260J Uout = (4.2)(370K) = 1554J P = ΔU/Δt = (1554J - 1260J) = 294 J/sec I don't know if this is correct. And I'm not sure how to approach (b), regarding entropy generation.
