3. A co generation power plant operating in a thermodynamic cycle at steadystate. The plant provides electricity to a community at a rate of 80 MW.The energy discharges from the

power plant by heat transfer is denoted on the figure by Q out: Of this, 70 MW is provided to the community for water heating and the remainder is discarded to the environment without use.The electricity is valued at $0.08 / kW-hr. If the cycle thermal efficiency is40%, determine: a) The rate energy is added by heat transfer Q in MW.in b) The rate energy is discarded to the environment, in MW c) The value of the electricity generated in $ per year.
