The acceleration of a high-speed aircraft is sometimes expressed in g's (in multiples of the standard acceleration of gravity). determine the upward force, in n, that a 140-kg man would experience in an aircraft whose acceleration is 6 g's the upward force the man would experience

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.
