An input voltage (the measurand) is connected to two voltage followers one after another. The supply voltages for the first one are +3 V and -2 V; the supply voltages for the second one are +2 V and -3 V. The output of the second voltage follower is connected to a voltmeter that can measure 0 to +10 V with a 0.1 V resolution. What is the resolution of the measurand?

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Fluids at rest possess no flow energy. a)- true b)- false

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.
