Unformatted text preview: The volume flow rate through a pipe is given by Q = vA , where v is the average velocity and A is the crosssectional area. Use volumecontinuity to solve for the required area in pipe 3. EGR 102 of 4 pages Lecture HW 01 3 Problem 3 (3 pts): For the freefalling parachutist with linear drag, assume a first jumper is 70 kg and has a drag coefficient of 12 kg/s. If a second jumper has a drag coefficient of 15 kg/s and a mass of 75 kg, how long will it take him to reach the same velocity the first jumper reached in 10 s? EGR 102 of 4 pages Lecture HW 01 4 Problem 4 (3 pts): Compute the velocity of a freefalling parachutist using Eulers method for the case where m = 80 kg and c d = 10 kg/s. Perform the calculation from t = 0 to 20 s with step size of 1 s. Use an initial condition that the parachutist has an upward velocity of 20 m/s at t = 0. At t = 10 s, assume that the chute is instantaneously deployed so that the drag coefficient jumps to 50 kg/s....
