A 120 galbon tank initially 90ib of salt dissolved in 90 gal of water brain containing 2ib/gal of salt flows into the tank at the rate of 4 gal/min and the well stired mixture flows out of the tank at the rate of 3 gal/min how much salt does the tank contain what is full

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.
