You are the engineer asked to design a rapid sand filtration system for a small water treatment plant. it has the following characteristics: hydraulic loading rate = 6 m/h total volumetric flow rate of the plant = 3 mgd effective filtration rate = 5.8 m/h production efficiency = 97% complete (filtration, rinsing, and backwashing) filter cycle duration = 48 h a) what is the area of your square filtration system? what are the surface dimensions of the filter? b) what volume of water is needed for backwashing plus rinsing the filter in each rinsing cycle?

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.
