thermodynamics applies to all forms of energy and has to do with the disorder of the system; entropy. Entropy can be produced‚ but never destroyed. In the universe entropy never decreases. Entropy in units of kilojoules per kilograms kelvin is equal to the enthalpy in kilojoules per kilogram divided by two times the absolute temperature in units of kelvin. There are two similar statements pertaining to the second law of thermodynamics. The first theory of the second law of thermodynamics was made by Nicolas

water and metal in hot water bath: | 100.3 °C | 100.3 °C | 100.3 °C | Final temperature reached in the calorimeter: | 27.5 °C | 32.2 °C | 28.0 °C | Part 1&2: Part I: 1. Calculate the energy change (q) of the surroundings (water) using the enthalpy equation qwater = m × c × ΔT. We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL. qwater = m × c × ΔT m = mass of water = density x volume = 1 x 26 = 26 grams ΔT = T(mix)

DESIGN OF TESLA TURBINE Abstract:- The Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla in 1913. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine. The Tesla turbine is also known as the boundary layer turbine‚ cohesion-type turbine‚ and Prandtl layer turbine (after Ludwig Prandtl). Bioengineering researchers have referred
