Question 1: A 50 mm diameter‚ thin wall metal pipe covered by 25 mm thick layer of insulation (ki = 0.085 W/m.K) and carrying a superheated steam at atmospheric pressure is suspended from the ceiling of a large room. The steam temperature entering the pipe is 120 oC‚ and the air temperature is 20 oC. The overall heat transfer coefficient on the outer surface of the covered pipe is 10 W/m2.K. if the velocity of the steam is 10 m/s‚ at what point along the pipe will the steam begin condensing and

Agiapal Sandhu Engl 100 November 12‚ 2014 Introduction A turbofan engine is found on all commercial airliners around the globe. The turbofan engine works by way of a thermodynamic cycle where air is taken into the engine‚ then compressed‚ combusted‚ expanded‚ and finally exhausted out of the engine. This creates thrust in the engine and causes the vehicle to propel forward or backwards. These steps are carried out by the

Title of Experiment 12: The Effect of Ionic Strength on the solubility of an Electrolyte Aim: The purpose of this experiment was to determine the thermodynamics variable of enthalpy‚ ∆H for the dissolution reaction of boric acid in water. The solubility of boric acid was measured over a range of various temperatures by finding out at what temperature crystallization began for solution of different molarities. A graphical relationship between the natural logarithm of molal concentration and the inverse

Temperature contrast between the equator and the Arctic region is greatest in the winter. Temperatures near or at the equator only change a few degrees between winter and summer while the Arctic region changes drastically up to 40 degrees between the seasons. 2. (a) Were latitude the only

determining heat of capacity of a calorimeter and measuring enthalpy of change for three reactions. It also enforced methods of analyzing data obtained through experimentation and calculating enthalpy. These procedures are used in the branch of thermodynamics known as thermochemistry which is the study of energy changes that accompany chemical reactions. Concepts from this lab can be used to determine the potential energy of a chemical reaction. Much of the energy people depend on comes from chemical

Barometric and air pressure is the weight of the air pushing down on the earth‚ the air below‚ and even the ocean. Atmospheric pressure is also known as air pressure. Also there is no air pressure on the moon do to not having low or no gravity. 3. What are the principal gaseous components of the earth’s atmosphere? Where do scientists believe these gases came from?

were to use wind energy‚ it would mean blocking the natural speed of a certain current. Its intensity would reduce after it would have crossed the windmill. As a result‚ the pressure equilibrium that it was meant to bring about will be affected. Atmospheric pressure is directly related to the weather conditions and hence the environment‚ in total. Thus‚ the quest to bring about economic growth
