this technology. The three most common OTEC systems are open cycle‚ closed cycle and hybrid cycle‚ all requiring all requiring a working fluid‚ condenser and evaporator within the system. These three systems all employ the thermodynamics of a working heat exchanger and use the temperature differences naturally occurring in the ocean as the driving force. A. Closed-Cycle D ’Arsonval ’s original concept formed the first closed-cycle OTEC plant system. This cycle uses a working fluid with

Sufficient Homemade Air Conditioner Introduction and Background of the Study As day time is starting to become more and more unbearable‚ as fans would only constantly stir the hot sticky air S around‚ so the researchers ended up in choosing this topic. The researchers chose this topic mainly because of the hot weather here in the Philippines. The constant high temperature was the reason this came up to the researchers’ minds. This

using this because the thermometer with a cork fits it and also to hold the water. Water: to use as the substance to contain the heat given off by each fuel Spirit burner: I am using this to safely burn the fuels Thermometer with a cork: I am using a thermometer to take the temperate of the water. The reason I am using one with a cork attached is to keep in as much heat as possible. Timer: I am using the timer to make sure I burn the fuel for the right amount of time Measuring cylinder: I am

follows: When the ignition‚ rotary kilns occur blasting because of low temperature‚ the reason is a low ignition temperature in the kiln‚ with coal combustion is bad‚ when the coal falls to a certain extent ‚burning fierce‚causing local concentration of heat‚ blasting phenomenon occurs. Prevention method is to maximize improve the ignition temperature‚ reducing coal consumption‚ shorten the ignition time. The rotary kiln in the application area‚ the numbers to be most cement industry. The whole process

also many of the enzymes that cause for undesired changes in the food cannot function properly at low water or no water level. But during drying there are two mechanisms which take place in the food‚ firstly heat is transferred to the food to provide sufficient amount energy for latent heat of vaporisation and secondly mass transfer is taken place as the water goes away from the food stuff (Earle‚ 1983). The Rate of drying depends on the type of food‚ the processing conditions and the design of

The importance of behavioral adaptations in turtles to thermoregulation and survival Katherine Whitehead Biology 301 Lab 7/15/13 Abstract Thermoregulation is necessary for ectotherms to survive. One important mechanism for thermoregulation seen in turtles is the ability to migrate between land and water habitats. This mechanism was studied using I-button data loggers placed inside marshmallow peeps to record temperatures in two different microhabitats; one in a stream and the other on the

Evolution allowed primitive forms of life to develop proteins and enzymes that made it possible for life to evolve under environments with hostile conditions‚ such as high salt and heat. More specifically‚ some bacteria selected genes that code for peptides with stronger intermolecular forces‚ coping with extreme heat‚ or for compatible solutes‚ which accumulate to compensate osmotic stress. The present study utilizes multiple bacterial strains to assess their ability to overcome unfavorable conditions
