float-type carburetor‚ the purpose of the economizer valve is to Provide a richer mixture and cooling at maximum power output 3. The fuel metering force of a conventional float-type carburetor in its normal operating range is the difference between the pressure acting on the discharge nozzle located within the venture and the pressure Acting on the fuel in the float chamber 4. If the main air bleed of a float-type carburetor becomes clogged‚ the engine will run Rich at rated power

Is the electric car the car the future? The main reason to buy an electrical car is the reduced CO2 emission. Reducing pollution coming from cars is a great way to fight global warming. It’s not only less pollution it also costs less. Each kilometer you drive in an electric car costs considerably less than with a comparable fuel car. The motor of an electric car also has a great advantage point with its speed. Electrical engines have a one gear box motor‚ it doesn’t have to shift gears. This

For a manager is a business setting it is important for them to understand how market equilibrium is maintained. Simple economic principles such as supply and demand are crucial in the business world when it comes to everything‚ especially making very important day to day decisions. The Process The intersection of the supply curve and the demand curve is considered market equilibrium and the price point (investopedia‚ 2012). This is another way of saying that the economic forces are balanced

LONG-RUN EQUILIBRIUM OF A FIRM UNDER PERFECT COMPETITION In the long run‚ a firm in the perfectly competitive market can earn only normal profit. So‚ the profit maximization under long run is: (1)Necessary condition P=LMR=LAR=LMC=LAC (2)Sufficient condition Slope of MC > Slope of MR We can establish this condition from the following analysis. In the above diagram for any market price OP1 the existing firms can earn supernormal profit as for the equilibrium output level OQ1. The average

Introduction: Chemical equilibrium is when the concentrations of the reactants and products have reached a state where reactions occurring in one direction are at the same rate of reactions occurring in the opposite direction. This process‚ called dynamic equilibrium‚ is the main subject of Le Chatelier’s Principle. Le Chatelier pointed out that if a system at equilibrium is subjected to a stress that momentarily causes the system to be not in equilibrium‚ a spontaneous change will occur to
