Assuming there are both a pressure gage and a manometer attached to a gas tank which has a pressure lower than Patm. If the reading on the pressure gage is 10kPa and atmospheric pressure is 100kPa, determine (a) the absolute pressure of the tank, and (b) the height of the fluid between the two fluid levels in the manometer, given the fluid is has a specific gravity of 1.5. Please calculate (a) the energy of a 1150-kg car consumes if it is driving at a velocity of 20m/s and a 100 m-long uphill road with a slope of 10degree; (b) the power is will require if the car is accelerating from 2m/s to 10m/s in 0.5s on a flat road. Disregard friction, air drag, and rolling resistance. Considering a river flowing toward a lake which is 40 m below. It is known that the river flows at a constant velocity of 5 m/s at a rate of 3 m3/s. Ignoring the flow energy, please determine: (a) the total specific mechanical energy of the river water; (b) the maximum power it can generate of the river at that location. A fan is to accelerate quiescent (velocity is 0 m/s) air to a velocity of 10m/s at a rate of 3 m3/s. If the density of air is 1.15 kg/m3, determine the minimum electric power that must be supplied to the fan.
