Production Capacity It is highly imperative that management must formulate a strategic plan for operations before any production is carried out. This is basically important in avoiding possible hindrances and excess in capacity. Under capacity may force the firm to cancel production schedules or excess can be fatal due to a broadened fixed cost. Both really would be a financial burden to the firm. Some procedural strategy can be adopted to minimize ill effects of capacity-related problems

MADALANG‚ Kyle Marron A. kyle.madalang@yahoo.com E302: Heat and Calorimetry METHODOLOGY The experiment was conducted following a two part procedure as follows. In the first part‚ the procedure aims to determine the specific heat of metals‚ specifically‚ the brass and aluminum‚ both undergone the following procedure‚ irrespective of their kind to which shall be used first. First‚ the mass of the metal ()‚ the inner calorimeter () and the water () in the calorimeter in grams was determined through

Specific Heat: The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat. The relationship does not apply if a phase change is encountered‚ because the heat added or removed during a phase change does not change the temperature. Q=mcTDelta Abstract: In this experiment we are trying to determine the

can the specific heat capacity of water be used to regulate temperature? Specific heat capacity is the amount of energy needed to increase the temperature of an object by 1˚C. The formula that uses specific heat is Q = mc∆T‚ where Q is heat energy‚ c is specific heat‚ and ∆T is the change in temperature. The amount of heat energy depends on the mass‚ or the size of an object‚ and the specific heat capacity‚ which depends on the substance it is made from. The specific heat capacity of water is 4

To name a few; the log mean temperature difference‚ heat transfer coefficient‚ Reynolds‚ Nusselt and Graetz numbers. The main focus of this experiment is the heating and cooling of the oil fluid. This was achieved using the heating component in the heat exchanger and water flowing

“Is Density An Intensive Property Of Matter?” By: Mikal Hayden - Gates A. Introduction The first unit we learned in chemistry was Alchemy. In this unit I learned about the extensive and intensive properties of matter. An extensive property is a property of matter that depends on the changes of the substances shape or amount. An intensive property is a property of matter that doesn’t depend on the substances shape or amount. The purpose of this investigation was to prove that density is
