activities were the lowering energy costs in the home. People sometimes think this to be hard but here are some good steps to follow to make it seem it easier. Reset the water heater thermostat‚ people do not always realize that most water heaters heat water to a set temperature and then hold it there‚ meaning that throughout the day and night the water heater cycles on and off‚ just maintaining that already set temperature. If we were to go the water heater and lower the setting a few degrees it

2.2 Peltier Thermoelectric cooler (TEC) Peltier thermoelectric heat pump is a popular thermoelectric energy conversion module that applies the Peltier effect‚ transferring heat energy from one side of the device to the other side. Peltier effect occurs when two different semiconductor materials (n-type and p-type) are joined together with electric current passing through its junction. Therefore‚ the junction could either be cooled or heated [28]. The Peltier TEC device can behave like a temperature

Insulin pumps send insulin through a small catheter continuously in small doses. This is places in a subcutaneous area and stays there for 2 or 3 days. The insulin pump is usually placed in the abdomen area or the buttocks. When it’s time for meals or snacks the patient can push a button which sends a bolus of insulin. This method is for patients who wants to have good control of the glucose levels and have a flexible lifestyle. Oral hypoglycemic medication is for patients who have type 2 diabetes

Introduction Softub Canada began in 1990 as a distributor for Softub USA. The product is a portable foam hot tub with pump and hydro-therapy jets. It can be plugged into any household 120 volt receptacle. It is covered with marine vinyl and totally self contained. The product was developed in the mid-1980’s and the U.S. manufacturer‚ holds several patents relating to its heating system. Since those early years the company has evolved from a distributor‚ to an assembler‚ into a full scale manufacturing

Geothermal Energy Introduction The Geothermal is a clean and sustainable (renewable) energy. It has been estimated that the heat of the centre of the earth may reach 6000°C. It has been found that the increases one degree °C for 30-50 meters. The word geothermal is derived from Greek language where the first syllable “Geo” means “earth” and the second syllable “thermal” means “heat”. How it works The geothermal energy should be made useful through electrical generators. We are not free to dig anywhere

COMSATS – LANCASTER (Dual Degree Program) EEE-112 Engineering Mechanics and Thermodynamics Assignment # 1 Submission date: Mon‚ Sep 17‚ 2012 1. A certain fluid at 10 bar is contained in a cylinder behind a piston‚ the initial volume being 0.05 m3. Calculate the work done by the fluid when it expands reversibly: a. at constant pressure to a final volume of 0.2 m3; b. according to a linear law to a final volume of 0.2 m3 and a final pressure of 2 bar; c. according to

Types of energy: kinetic e(in joules)= .5mv^2. Solar energy- 1gw per km^2 Solar energy can be turned into electricity through solar cells 15%=cheap‚ 40% efficiency=expensive. Caloric theory of heat=caloric fluid flows from hot object to cold. Heat engine= device to turn heat energy into useful work: heat comes from something hot but only some goes to useful work. Satellites=free fall. Ionizing radiation=energy in the form of waves or paricle Beta radiation-just an electron‚ wont go through skin

Pump Boys and Dinettes This musical was performed at the Triad Stage in Greensboro‚NC. Starting April 6th-May4th. Directed by Bryan Conger. The setting of this play was at a gas station/ diner where 4 auto handy men worked along with 2 dinette ladies. They sing about their lives at the Double Cupp Diner and Pump Boys Auto Shop and the lives they wish they could have. These country characters feature roles that audience members can relate to which makes this play so interesting. Pump Boys

Compressors are similar to pump‚ both increase the pressure on a fluid and both can transport a pipe. As gases are compressible‚ the compressor also reduces the volume of a gas. Liquids are relatively incompressible‚ while some can be compressed‚ the main action of a pump is to pressurize and transport liquids. Types of compressors The main types of compressors are shown below: Compressor types Positive displacement Dynamic 1. Reciprocating. 2. Rotary 1.Centrifugal. 2. Axial
