Experiment 1: Pressure, Temperature, and Velocity Measurement Objective: The objective of this experiment is to determine the pressure and density of laboratory air, calibrate a pressure transducer and scannivalve, then determine the test section speed as a function of fan speed using three methods of velocity measurement. Equipment: Absolute pressure transducer, digital thermometer, pressure transducer (voltmeter), micromanometer, scannivalve, Pitot tube, low-speed wind tunnel. Part 1: Measurement of Atmospheric Pressure and Density 1. Read the barometer and wind-tunnel thermocouple. 2.
Isherwood has demonstrated a systematic method by which empirical coefficients can be calculated by analysing measured data through multiple regression techniques. Fig. (2) shows the effect of wind moving at a speed of 20 m/sec at 10 m height on a ship having length and breadth of 100 m and 20 m respectively
Name: 6.03: Calorimetry Data and Observations: Part I: Insert a complete data table, including appropriate significant figures and units, in the space below. Also include any observations that you made over the course of part I. (4 points) I observed that when the metal is placed inside the calorimeter, it transfers heat to the water making the water increase temperature while the metal will decrease temperature. I also noticed that the system was the metal and the surroundings is the water, this is because the water is taking in the heat from the metal making the water warm. Metal Name Mass of Metal Volume of water Initial temp.
This lab shows how materials react to heat energy inputs and how far this energy spreads along the substance relative to the energy lost, along with allowing us to calculate the thermal conductivity. Thermodynamics are an essential part of the functioning of engines, therefore the automotive industry relies on the understanding and the application of thermodynamics. Some motorcycles still use air cooling however most automobiles now use form of liquid cooling. A car radiator is a good example of a heat sink through use of a coolant. Coolant flows around the engine once the engine has heated up to is optimum temperature, taking heat from the engine.
This can be described as a substance that produces energy to its surroundings. An example of an exothermic reaction could be when gas burns in an engine. In my lab I studied both endothermic and exothermic reactions. I did this by adding substances together to produce each reaction. I recorded the reactions using the Logger Pro computer program and a temperature probe.

Then the energy loss due to the jump will be evaluated, using the energy equation. 2.0 OBJECTIVE To investigate the characteristic a standing wave (the hydraulic jump) produced when waters beneath an undershot weir and to observe the flow patterns obtained. 4.0 THEORY When water flowing rapidly changes to slower
The transfer is often influenced by the Hydrologic cycle (water cycle). At many stages of the cycle, water changes in state. For instance, the evaporation of water from a lake will become vapour during the Hydrologic cycle. Whenever water molecules undergo a change in phase, thermal energy will be released or absorbed. Thermal energy is released when water goes from a liquid to a solid.
In this paper we propose measuring these fluctuations using the fractal dimension. To estimate this parameter the Rectangular Covering Method we already developed is used. The method applied to hourly wind speed of Quebec station provides information that allows us to characterize the wind speed variation at this location Keywords: Fractal dimension, rectangular covering method, Minkowski-Bouligand method, log-log plots, least squares estimation, wind speed, fluctuations, wind energy. 1. INTRODUCTION A major issue in the control and stability of wind energy production systems is to maintain the balance between generated and consumed power.
Jet pumps circulate the coolant water along the individual fuel rods in each fuel assembly in the core where it boils and becomes a two part steam- water mixture. Another difference between the two reactors is the pressure in the systems. In a pressurized water reactor the pressure in the system varies from the primary system to the secondary system. In the primary system, the pressure is kept at 2250 psi to
