Dilute sulfuric acid (19% acid and the rest water) is required for activating car batteries. A tank of weak acid (12.5% acid and the rest water) is available.

If 450 lbs of 78% concentrate acid is added to the tank to get the required 19% acid, how much of the 19% acid is now available?

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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.
