4.) Each of the four jet engines on an Airbus A380 airliner develops a thrust (a forward force on the
airliner) of 322,000 N. When the airplane is flying at 250 m/s, what horsepower does each engine
develop?
If there are five different Carnot engines (C1, C2, C3, C4 and C5) with low temperature
reservoirs are at 7 "C, 10 °C, 13 "C, 15 °C and 18 °C respectively and each engine has
efficiency of 60%. It is desired to increase the efficiency of each engine to 75 %. By using the
selections statements calculate that how many degree the temperature of the source of each
Carnot engine be increased separately. Do a subplot of bar and stem Plot of the temperature
of the source against each heat engine Cl, C2, C3, C4 and C5.
[Hint: Efficiency of heat engine is , Use else if else as selection statement. And take all
the inputs by using input command and take all the outputs by using fprintf command.]
3. Please calculate the annual electricity production of a wind farm with 20 turbines. The annual
mean wind speed is 7 m/s and diameter of the blades is 20 m. If we assume power
consumption of a person is 3,000 kWh, about how many people will this energy support?
Annual electricity production (KWh) = K Vm³ At T
Where:
-
-
-
K = 3.2 (factor based on turbine performance)
Vm= annual mean wind speed (m/s)
At = swept area of turbine (m2)
T = number of turbines
Suitable for medium- to large-scale wind turbines (> 200 m2 swept area)

- 2. Some of the first power-generating wind turbines were small, having blades with a radius of 8.00 meters. Currently, the largest wind turbine has a radius of 164 meters. Because the small wind turbines are closer to the ground, they often experience smaller wind speeds. Given the information below, how many small wind turbines would be needed to produce the same power output as one large wind turbine? For both wind turbines, assume the air density is 1.23 kg m³.
