An oil fired steam generator is connected to a steam engine which produces 50kw of power when using oil of energy content 47mj/kg at a rate of 19.9kg/h. steam temperature is500c and cooling water temperature is 15 c. calculate the: a. heat rejection rate. b. the ovrerall efficiency of the plant. c. maximum efficiency attainable by the engine.

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
