`A 20cm diameter pipe of length 100m with z = 60m with f = 0.02 and loss of head due to entrance coefficient k = 0.5. What is the flow rate? Solution: Find the width in m of the channel at the back of a suppressed weir using the following data: H = 28.5cm; d = 2.485m; Q = 0.84 cu.m/sec. Consider the velocity of approach and use the Francis formula. Solution: Water flows in a 2m. wide rectangular flume at the rate of 2.75 cu.m./sec

The mathematical expression for Boyles Law is: V=K(1/P) or PV=K (Constant T and n) Where‚ P and V are the pressure and volume of the gas sample respectively. K is a constant and dependent of the temperature (T) and the amount of gas (n‚ moles). The Graph below successfully indicates Boyle’s Law visually: A: Volume Verses Pressure B: Volume Verses 1/P Part

change in temperature and pressure of ethanol using a Vernier temperature probe. By using the ideal gas equation‚ and plugging the slope value from the graph into the Clausius-Claypernon equation‚ enthalpy of vaporization was determined to be 10kJ/mol. The percent error was determined to be 76.0%. Introduction: The purpose of this lab is to investigate vapor pressures and the partial pressure of gas produced from liquids at different temperatures. These pressures vary at different temperatures

Social expectations are something every person faces. No matter one’s gender‚ ethnicity‚ or class‚ everyone feels pressure to behave a certain way‚ and I believe one of the most defining character traits is whether one chooses to conform to these social pressures or to pave his or her own path in life. Despite the existence of social norms in every culture‚ certain cultures hold these expectations in much higher regards than others‚ and breaking such social laws can have detrimental consequences

ABSTRACT This experiment was carried out to determine the relationship between the pressure and the temperature of saturated steam in equilibrium. Besides that this experiment was also done to demonstrate the vapor pressure curve. The marcet Boiler was used for this experiment. When the pressure increases‚ the temperature also increases. Therefore‚ the relationship of pressure and temperature is directly proportional. The derived formulae and the data were used to calculate the slope. The dT/dP

On a microscopic level‚ the molecules (or atoms) in a gas are separated by large distances and are in constant‚ random motion. When dealing with gases‚ the Ideal Gas Law equation is the most famous equation used to relate all the factors in dealing and solving the problem. The four factors or variables for gas are: pressure (P)‚ volume (V)‚ number of mole of gas
