Using MATLAB

Problem 17 Plot the following function yex) in the interval -12 SxS7 10 points -0001-0.0102+ 4-s Problem 18: Open Channel Discharge Factor The discharge factor for flow through an open channel of parabolic cross-section is given by 1-23 1.2 4x where x is the ratio of the maximum water depth to the breadth of the channel at the top of the water. Determine K when r0. 45. Problem 19:Air Flow in Rectangular Du Air flow in a rectangular duct with sides of length A and B has an equivalent flow resistance to that of a circular duct of diameter D, which is given by the following equation: (AB) S D = 1.2651 Use MATLAB to find the value ofD when A1.7 m and 1.2 m. 115 points Problem 20: Energy released in an Farthquake The Richter scale is a measure of the intensity of an earthquake. The energy E (in Joules) released by the quake is related to the magnitude M on the Richter scale as follows Use MATLAB to find how much more energy is released by a magnitude 7.6 quake, than by a 5.6 quake
