Consider a river flowing toward a lake at an average speed of 3 m/s at a rate of 550 m3/s at a location 58 m above the lake surf
Vladimir [108]

Answer:

1. 0.574 kJ/kg

2. 315.7 MW

Explanation:

1. The mechanical energy per unit mass of the river is given by:

E_{m} = E_{k} + E_{p}

E_{m} = \frac{1}{2}v^{2} + gh

Where:

Ek is the kinetic energy

Ep is the potential energy

v is the speed of the river = 3 m/s

g is the gravity = 9.81 m/s²

h is the height = 58 m

E_{m} = \frac{1}{2}(3 m/s)^{2} + 9.81 m/s^{2}*58 m = 0.574 kJ/Kg

Hence, the total mechanical energy of the river is 0.574 kJ/kg.

2. The power generation potential on the river is:

P = m(t)E_{m} = \rho*V(t)*E_{m} = 1000 kg/m^{3}*550 m^{3}/s*0.574 kJ/kg = 315.7 MW

Therefore, the power generation potential of the entire river is 315.7 MW.

I hope it helps you!

gogolik [260]

Answer:

C. dismiss them.

Explanation:

The American Psychological Association is a scientific organization and it serves as an umbrella body for the professional psychologists practicing in the United States of America. This professional organization was founded by Granville Stanley Hall in July, 1892 and it has become the largest professional body with over 120,000 members such as scientists, consultants, clinicians, educators etc.

Basically, the American Psychological Association is saddled with the responsibility of providing professional certifications to psychologists and assisting in the advancement of human well-being.

If a psychologist violates his or her ethical obligations but breaks no laws, the American Psychological Association could take action and dismiss or censure them. This is done so as to serve as deterrent to other psychologists and to help maintain the core values, objectives and mission of the professional organization.
