Homework #6 – due nov 12 (tuesday) a gas stream consisting of 65 mole% h2, 34.5 mole% co, and 0.5 mole% ch4 is fed to a process to synthesize methanol (co + 2h2 → ch3oh). the stream from the reactor is fed to a condenser where essentially all of the synthesized methanol is condensed and all of the unreacted gases are recycled back to the reactor. to avoid a buildup of methane, a purge stream is removed from the recycle. the overall conversion of co is 85% and the methane mole fraction in the reactor inlet [n3/(n1+n2+n3)] is 0.03. 1. find the amount of methanol produced by this process (n11). 2. find the fraction of recycle that is purged [np/(nr+np)]

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

Askydiver weighing 140 lb (including equipment) falls vertically downward from an altitude of 19,000 ft and opens the parachute after 18 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|v| when the parachute is closed and is of magnitude 14|v| when the parachute is open, where the velocity v is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. (a) find the speed of the skydiver when the parachute opens. (b) find the distance fallen before the parachute opens. (c) what is the limiting velocity vl after the parachute opens? (d) determine how long the sky diver is in the air after the parachute opens. (e) plot the graph of velocity versus time from the beginning of the fall until the skydiver reaches the ground.
