Brief history of demand curve and supply curve According to Hamid S. Hosseini‚ the power of supply and demand was understood to some extent by several early Muslim economists‚ such as Ibn Taymiyyah who illustrates- “If desire for goods increases while its availability decreases‚ its price

COOLING TOWER INTRODUCTION: Cooling towers are a very important part of many chemical plants. The primary task of a cooling tower is to reject heat into the atmosphere. They represent a relatively inexpensive and dependable means of removing low-grade heat from cooling water. The make-up water source is used to replenish water lost to evaporation. Hot water from heat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units

Global warming is commonly referred to as an increase in the temperature of the lowest layers of Earth’s atmosphere. Global warming has occurred in the distant past as the result of natural influences‚ but the term is most often used to refer to the warming predicted to occur as a result of increased emissions of greenhouse gases. Primary greenhouse gases include water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚ and ozone . Carbon dioxide‚ as well as other greenhouse gases‚ is a very important

There are a lot of methods of heat transference when cooking. The methods of cooking are classified according to how heat is applied. For example moist methods‚ dry methods ‚ frying and microwave. For example in moist methods of cooking‚ there is boiling‚ poaching ‚ par-boiling . Also steaming that is when the food doesn’t come in contact with the water but is cooked in the steam . The advantage is that there is loss of nutrients ‚easy to digest‚ light texture ‚little attention ‚ and the food
