Question as shown in picture. 5Нeat4Exchangerwater3Figure 2What is the specific isentropic work done of compressor in kJ/kg?а. 8.5b. 180.2c. 151.1O d. 147.8 Air enters an adiabatic air compressor with a pressure at 100 kPa, temperature of 30°C, and a steady volume flow rate of 3.0 m3/s. After compression, the temperature of the airis 180°C. The compressed air is then cooled in a heat exchanger, with liquid water as the cooling medium (not mixed with the air). The pressure of the air at the exit of the heatexchanger is 360 kPa. The water, flowing at a steady rate of 1.5 kg/s is heated from 30°C (Point 4) to 38°C (Point 5) in the heat exchanger. Figure 2 shows a schematic of theprocess.The following can be assumed:a. Air is an ideal gas with cp=1.007 kJ/kgK and R=0.287 kJ/kgKb. Liquid water is incompressible and has a specific heat of 4.18 kJ/kgKc. The pressure drop and the heat loss from the connecting pipes are negligible.d. The pressure drop in the heat exchanger is 40 kPa (i.e. NOT NEGLIGIBLE), and heat loss from the heat exchanger to the surrounding are negligibleа.Air1Compressor5

A sprinter practicing for the 200-m dash accelerates uniformly from rest at A and reaches a top speed of 36 km/h at the 76-m mark. He then maintains this speed for the next 61 meters before uniformly slowing to a final speed of 31 km/h at the finish line. Determine the maximum horizontal acceleration which the sprinter experiences during the run. Where does this maximum acceleration value occur? Part 1 Answers: (a) al- Finish line Calculate (a) the magnitude of the tangential acceleration near start of the race and (b) the magnitude of the tangential acceleration near the end of the race.
