Welcome to this lecture number 20 of our course on fundamentals of transport processes. . If you recall, in the previous lecture we had started solving problems involving transport in one dimension; unsteady transport in one dimension. So, we had considered the simple case of a fluid that is heated from below. Initially the system […]

dear students, let us study law of conservation of momentum now as we have already studied in the previous chapter , about system of particles, for a system of particle we have studied that velocity of centre of mass , of a system of particle can be given by , total momentum of system divided […]

Announcer: GENTLEMEN, START YOUR ENGINES! Crew Member: GREEN, GREEN, GREEN, GREEN… Griff Jones: THESE DRIVERS LOST CONTROL AT VERY HIGH SPEEDS. THE RESULT WAS TRAGIC FOR ONE DRIVER… AND FORTUNATE FOR THE OTHERS. BUT WHY? WHAT MADE THE DIFFERENCE BETWEEN WALKING AWAY AND BEING CARRIED AWAY? THE ANSWER CAN BE FOUND IN SOME OF THE […]

In my last video we performed an experiment in which two identical wood blocks were shot with the same rifle, one through the center of mass and the other one slightly off to one side. Now if you haven’t seen that video yet, then click here now and go and watch it. Or, if you […]

in this example we are given that a ball with a speed 9 meters per sec strikes, another identical ball at rest such that after collision, the direction of each ball makes an angle 30 degree with the original line of motion, and here we are required to find the speed of the two balls […]

You and your friend decide to spend the afternoon at the ice skating rink, but to mix things up, you decide to bring a 0.2 kilogram frisbee. Much to the irritation of the other patrons at the rink, you begin to toss the frisbee back and forth as you skate around. Given that you are […]

this example says that a figure shows a spring block system , on which time varying force , 5 t is applied on two k g mass, and after ten sec velocity of three k g mass is observed to be thirty meters per sec, we are required to find velocity of two k g […]
