Extracted text: dg A Consider the tank shown in (Figure 1), with water flowing in through pipe A and out through pipe B. The amount of water in the tank does not change with time, the diameter at A is da = 3.8 cm , the diameter at B is dB = 6.1 cm , and the average velocity at A is VA = 2.5 m/s , what is the average velocity at B? The density of water is pw = 1000 kg/m3 Express your answer in m/s to three significant figures. Now consider the same tank (Figure 1), with water flowing in through pipe A and out through pipe B. In this case, the amount of water in the tank is increasing at 0.8 kg/s Everything else is unchanged: the diameter at A is da = 3.8 cm , the diameter at B is de = 6.1 cm , and the average velocity at A is VA = 2.5 m/s, what is the average velocity at B? The density of water is Pw = 1000 kg/m³ Express your answer in m/s to three significant figures. В A Now consider a similar tank (Figure 2) full of air. Air flows in through pipe A and out through pipe B. The pressures and temperatures are PA = 150 kPa and TA = 20 °C at A and pB = 101 kPa and TB = 45 °C at B. The geometry is unchanged: the diameter at A is da = 3.8 cm and the diameter at B is dB = 6.1 cm . For this system, the average velocity at A is VA = 2.8 m/s and the average velocity at B is VB = 1.5 m/s . What is the rate of change of mass in the tank? The gas constant for air Rair = 286.9 kg-K Express your answer in kg/s to three significant figures.
