+//To estimate power lost in friction
+clc
+//Given:
+D=150/1000,R=D/2 //m
+N=100 //rpm
+W=20*1000 //N
+mu=0.05
+//Solution:
+//Calculating the angular speed of the shaft
+omega=2*%pi*N/60 //rad/s
+//Calculating the total frictional torque for uniform pressure distribution
+T=2/3*mu*W*R //N-m
+//Calculating the power lost in friction
+P=T*omega //W
+//Results:
+printf("\n\n Power lost in friction, P = %.1f W.\n\n",P)
