An automobile moving through the air causes the air velocity (measured with respect to the car) to decrease and fill a larger flow channel. An automobile has an effective flow channel area of 3.5 m2. The car is traveling at 90 km/h on a day when the barometric pressure is 70 cm of mercury and the temperature is 20°C. Behind the car, the air velocity (with respect to the car) is measured to be 82 km/h, and the temperature is 20°C. Determine the power required to move this car through the air and the area of the effective flow channel behind the car. Flow channel = The power required to move the car through the air is The area of the effective flow channel behind the car is | kW. m²

In a piping system at sea level, a liquid of relative density 1.5 flows through a pipe 8 cm in diameter.diameter at 1.2 m/s. Fifteen meters above the pipe diameter is reduced to 5 cm, Assume that the temperature of thefluid in the process remains at 30°C, producing a heat loss of 25 N-m/kg. Determine the pressure change in the thermodynamic process.
A soap bubble with a diameter of 2.72" is to be enlarged by blowing air into it. If the surface tension of the soap solution is 0.0035 Ibf/ft, determine the work input required to inflate the bubble to a diameter of 3.64". Express your answer in 8 decimal places and in Btu.
The American Society of Heating, Ventilating, and Air Conditioning Engineers (ASHRAE) sets the standard for outdoor air requirement for ventilation purposes. For example, for a gymnasium, an outdoor air requirement of 9.4 L/s per person is required. What is the total volume of the outdoor air that must be introduced into a gym during a 12-hour period if on average 30 people are using the gym every minute? Express your answer in liters and m3 .
The water level in a tank is 20 m above the ground. A hose is connected to the bottom of the tank, and the nozzle at the end of the hose is pointed straight up. The tank cover is airtight, and the air pressure above the water surface is 2 atm gage. The system is at sea level. Determine the maximum height to which the water stream could rise.
A soap bubble with a diameter of 2.88" is to be enlarged by blowing air into it. If the surface tension of the soap solution is 0.0038 lbf/ft, determine the work input required to inflate the bubble to a diameter of 3.61". Express your answer in 8 decimal places and in Btu.
A soap bubble with a diameter of 2.28" is to be enlarged by blowing air into it. If the surface tension of the soap solution is 0.0040 lbf/ft, determine the work input required to inflate the bubble to a diameter of 4.94". Express your answer in 8 decimal places and in Btu.
An air cannon uses compressed air to propel a projectile from rest to a final velocity. Consider an air cannon that is to accelerate a 10-gram projectile to a speed of 300 m/s using compressed air, whose temperature cannot exceed 20°C. The volume of the storage tank is not to exceed 0.1 m3 . Select the storage volume size and maximum storage pressure that require the minimum amount of energy to fill the tank.
