Variable Geometry Turbocharger Turbochargers works on the simple principle of increasing the intake air density by compression. Being able to fill more air into the combustion chamber will allow more fuel to be added to produce more power. However the operation of the turbocharger relies solely on the exhaust gas velocity to drive the compressor. Thus the compressor will be at optimum operation range when the engine is under heavy load. When the throttle is opened‚ it will take a certain period

paper helicopter affects the time it takes to travel a fixed distance Aim: Does the mass of an object affect the time it takes to travel a fixed distance? Introduction: This is an experiment to find out the relationships between mass‚ distance‚ velocity and time. Dependent Variable: The height where the helicopter is dropped from. Independent Variable: The velocity of the helicopter‚ the time it takes for the helicopter to travel down the fixed height and the mass of the objects on the end of the

The structure of the promissory note is that of a discount security‚ sold by the issuer for less than the face value in exchange for the face value at maturity (Viney & Phillips 2012‚ 308). The discount amount‚ which is the difference between the face value and the issue price‚ is the cost of borrowing to the issuer and the

Nationalisation of Banks Despite the provisions‚ control and regulations of Reserve Bank of India‚ banks in India except the State Bank of India or SBI‚ continued to be owned and operated by private persons. By the 1960s‚ the Indian banking industry had become an important tool to facilitate the development of the Indian economy. At the same time‚ it had emerged as a large employer‚ and a debate had ensued about the nationalization of the banking industry. Indira Gandhi‚ then Prime Minister of India

Chapter 7 Variable Costing: A Tool for Management Solutions to Questions 7-1 The basic difference between absorption and variable costing is due to the handling of fixed manufacturing overhead. Under absorption costing‚ fixed manufacturing overhead is treated as a product cost and hence is an asset until products are sold. Under variable costing‚ fixed manufacturing overhead is treated as a period cost and is charged in full against the current period’s income. 7-2 Selling and administrative expenses
