A projectile is launched at 25 degrees to the horizontal at an initial speed of 10 m/s. There is no propulsion on the projectile. Neglecting drag, how long will it take to reach peak altitude? How high
will it go? How far horizontally will the projectile travel?

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
