Is it possible to have a heat engine with efficiency of 100%?
Alex17521 [72]

Answer:

No

Explanation:

Heat engines are used for converting the heat into mechanical energy which is used for doing mechanical work.

The efficiency of heat engine is the fraction of mechanical energy to the thermal energy. The efficiency can not be 100% as some of the energy always loss due to friction and motion of the body parts of the heat engine.

A geothermal pump is used to pump brine whose density is 1050 kg/m3 at a rate of 0.3 m3/s from a depth of 200 m. For a pump effi
nasty-shy [4]

Answer:

Input power of the geothermal power will be 686000 J

Explanation:

We have given density of brine \rho =1050kg/m^3

Rate at which brine is pumped V=0.3m^3/sec

So mass of the pumped per second

Mass = volume × density = 1050\times 0.3=315 kg/sec

Acceleration due to gravity g=9.8m/sec^2

Depth h = 200 m

So work done W=mgh=315\times 9.8\times 200=617400J

Efficiency is given \eta =0.9

We have to fond the input power

So input power =\frac{617400}{0.9}=686000J

So input power of the geothermal power will be 686000 J
