Answer:

A supercapacitor, also called an ultracapacitor, is a high-capacity capacitor with a capacitance value much higher than other capacitors, but with lower voltage limits, that bridges the gap between electrolytic capacitors and rechargeable batteries.

Thrust is managed to maintain IAS, and glide slope is being flown. What characteristics should be observed when a headwind shear
SVEN [57.7K]

The characteristics that can be observed when a headwind shears to be a constant tailwind are:

  1. Pitch attitude: decreases.
  2. Required thrust: increased then reduced.
  3. Vertical Speed: increases.
  4. Indicated airspeed (IAS): decreases, then increases to approach speed.

<h3>What is thrust?</h3>

Thrust can be defined a force that moves an aircraft or a flying machine through the air, especially in the direction of the motion.

<h3>The importance of thrust.</h3>

Generally, thrust is used in aeronautic engineering to achieve the following:

  • To overcome the weight of a rocket.
  • To overcome the drag of an aircraft.
  • To maintain indicated airspeed (IAS).
  • To maintain glide slope being flown at.

Some of the characteristics that can be observed when a headwind shears to be a constant tailwind are:

  1. Pitch attitude: decreases.
  2. Required thrust: increased then reduced.
  3. Vertical Speed: increases.
  4. Indicated airspeed (IAS): decreases, then increases to approach speed.

Lynna [10]

Answer:

a) 0.76

b) 0.80

c) 1964 kW

Explanation:

GIVEN DATA:

\dot m = 5000 kg/s

Assume Mechanical energy at exist is negligible

A) Take lake bottom as reference, and then kinetic and potential energy  are taken as zero.

change in mechanical energy is givrn as

e_{in} - e_{out} = \frac{P}{\rho} - 0 = gh = 9.81 \times 50( \frac{1 kJ/kg}{1000 m^2/s^2}

                         = 0.491 kJ/kg

\Delta \dot E_{mec} = \dot m (e_{in} - e_{out}) = 5000 \times 0.491 = 2455 kW

\eta_{OVERALL}  = \frac{\dot W}{\Delta \dot E_{mec}} = \frac{1862}{2455} = 0.76

B) \eta -{gen} = \frac{\eta_{overall}}{\eta_{gen}} = \frac{0.76}{0.95} = 0.80

c) \dot W_{shaft} = \eta_{overall} \left | \Delta \dot E_{mec} \right | = 0.80(2455)

\dot W_{shaft} = 1964 kW
