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.
It is a heat engine that converts energy into mechanical energy. It makes use of the fact that steam, when passing through a small opening that attains a high velocity. Condenser The condenser is a major component of the power plant where it receive exhaust steam from the last stage of the turbine and condenses it to water for reuse as feed water in the boiler system. It can be classified under a direct contact type or a surface condenser. Other component(s) includes: Pressure gauge Steam turbine valve Burner switch Water level gauge c) (iv) The Rankine cycle efficiency Assume steady flow, KE = PE = 0 From a 1st law balance, we know energy in = energy out ------------------------------------------------- Device 1st Law Balance
Describe the appearance of the flame when the air vents are opened. When the air vents (collar) are opened, the air mixes with the gas and makes a more complete combustion reaction. This results in a hotter reaction, with a light blue colored flame. 6. What apparatus is used in this demo to test how hot the flame is?
Think of a hot air balloon, for instance. If you increase heat in the hot air balloon, it will increase in size and pressure. We have equipment to measure temperature and pressure of the liquid and gas. A LabQuest/LabQuest App measures the temperature and it measures the pressure for us instantly in the units we need. A Vernier gas pressure sensor can be used to measure changes in pressure of a gas.
One of the fluid is considered as the hot fluid and the other fluid is the cold fluid. The hot fluid will transfer its heat to the cold fluid in the Heat exchanger. 1.1 TYPES OF HEAT EXCHANGERS * Air Cooled * Double Pipe * Spiral Plate and Tube * Shell and Tube 1.2 HEAT EXCHANGER TYPES Heat exchangers are ubiquitous to energy conversion and utilization. They involve heat exchange between two fluids separated by a solid and encompass a wide range of flow configurations. Parallel Flow Counter flow Figure No 1.1 * Simplest configuration.
The water vessel is attached to the heat source by metal rods, which heat the water directly and convert it to steam. The steam initially collects in an area above the water vessel known as the dome before exiting the boiler. The dome forces the steam to become highly condensed so that it will exit the boiler with a significant amount of pressure. Pressurized steam is particularly important for industrial applications such as powering turbines and other heavy equipment. All boilers have a safety valve, which allows excess steam to be released to prevent explosions.
