Example 1 Nozzle Flow - Steam Steam at 1.5 bar and 150 deg C enters a nozzle at 10 m/s and exits at 1 bar. Assuming the flow is reversible and adiabatic‚ determine the exit temperature and velocity. If the exit nozzle area is 0.001 m2‚ evaluate the mass flow rate of the steam through the nozzle. P1 = 1.5 bar T1 = 90 deg C V1 = 10 m/s A2 = 0.001 m2 P2 =1 bar T2 = ? V2 = ? mdot = ? V2 = sqrt(V1*V1+2*(h1-h2)) mdot = rho*A2*V2 = A2*V2/v2 T2 382.60 m/s 0.22 kg/s 111.81 degC Superheated

Understanding the Thermodynamics of Titrated Borate. Alexis Cervantes and Ak Young. CHEM 114-07 April 30‚ 2024. Introduction The purpose of this experiment was to evaluate thermodynamic values and understand their relationship to equilibrium constants. By measuring the change in enthalpy (H°) and the change in entropy (S°)‚ the equilibrium constant (Ksp) was determined for the dissolution of borax in water. In procedure one of the experiment‚ the temperature of the borax solution was varied

The two studies by Dehaene-Lambertz‚ Dehaene‚ and Hertz-Pannier (2002)‚ as well as‚ Homae‚ Watanabe‚ and Taga (2014) will be compared. The studies measure the perception of speech sounds in the infant brain using functional magnetic resonance imaging (fMRI). Each set of researchers collected data from young infants around 3 months. Different qualities of sound were presented to the infants in order to measure the activation of certain structures in the brain. The hemodynamic responses to different

exothermic reaction is a chemical reaction that releases heat. Design: Research question- Which reaction occurs‚ exothermic or endothermic‚ when Epson salt‚ Borax‚ Laundry detergent‚ and baking soda are added‚ separately‚ with water? Hypothesis- If Epson salt is mixed with water then the reaction will be endothermic because salt is used to melt ice. If Borax is mixed with water then the reaction will be endothermic because it’s associated with heat and fire. If laundry detergent is mixed with water‚ then

There is no creation of energy‚ and thus no violation of the conservation of energy principle. 1-3C There is no truth to his claim
