Response to Question 1

The height in meters above Sea Level at the Point of observation is 960 meters MSL equivalent pressure MSL equivalent pressure also abbreviated as pMSL pMSL = pobs + pgzobs It is important to acknowledge that p is the density of air at the point of observation and g is the acceleration due to gravitational force and z is the height at the point of observation. In this case, p (density of air at the point of observation) = 1.2041 kg/m3; while g (acceleration due to gravity) = 9.81m/s2. The height in meters (z) at the observation point is 196 meters.

Taking these figures into consideration, pMSL will be attained as indicated below;

pMSL = 1.2041 + ( ...

Introduction

The object of the paper is to analyze the above relationship over a range of pressures extending above and below atmospheric pressure. Data were obtained for the pressure and temperature of a saturated steam-water mixture in equilibrium over a wide range of pressures and temperatures. The “raw” experimental data are given at the end of this document and the apparatus used are described below.

The object of this exercise is to:

a) Use the raw data to produce a table of absolute pressure .v. absolute (thermodynamic) saturation temperature over the whole range of the data provided. b) Compare this data to equivalent data taken from steam tables. c) Use ...

Abstract

The fugacity is a term that has Latin origins, referring to pace and speed. Early work somewhere in the 20th century, on fugacity, demonstrated that chemical equilibrium is established by the free energies of reacting material. Since then, various approaches and concepts on fugacity have been provided. The gas fugacity of noble gasses has been studied, and models have been proposed for calculating the solubility of noble gasses. The development of various models has considered pressure effects, differential equilibrium between components and temperature changes. The paper discusses the evolution of various multimedia fugacity models and the fugacity of pure ...

Abstract

The experiment aimed at monitoring the change in volume of a gas in a confined container as the pressure on the gas was being increase. The experiment successfully demonstrated that volume decreases as the pressure on gas is increased.

Introduction

Boyle’s Law involves the relationship that exists between volume and pressure of an ideal gas, assuming that the mass and temperature of the gas is held constant. The law is stated that for a fixed ideal gas amount kept at a fixed temperature, pressure (P) and volume (V) are inversely proportional. This means that when one parameter is increased, the other one decreases. ...

Abstract

The experiment aimed at explaining the interaction of the molecules at different pressure, temperature and volumes. At low temperatures, the volume of the gas was low while at high temperatures, the volume of gas increased. The experiment successfully determined the value of absolute temperature using the Charles’s Law as 202.75OC which was lower than the theoretical value. The experiment also successfully verified the Boyle’s Law. The interaction of temperature and the volume of the fluid can be concluded to be directly proportional with an increase in temperature leading to increase in volume. On the other hand, the ...

According to ideal gas law, PV = nRT For a constant mass, isobaric process, V/T = nR/P = constant. Hence, V1/T1 = V2/T2. For each of the cases, V1/T1 = 1/300 dm3/K. V2/T2 has been calculated in the table below for each case.

1. Thermodynamics Thermodynamics, according to mechanical engineering, falls under the fourth semester with a code of MME 2010(3). As a branch of mechanical engineering, it deals with study of the effects as a result of work done by or on material bodies or radiation in space. It is mainly concerned with the interrelationship between the three existing macroscopic variables, temperature, heat, and pressure in reference to the description of physical properties of the radiation and material bodies. Radiation in space and material bodies, are mostly referred to as thermodynamics system. Thermodynamics can be therefore be described succinctly as the ...
