1. a power plant operates with a simple rankine cycle with water as the working fluid. the plant operates with a high pressure of 1400 psia, and a low pressure side at 2 psia. the pump has an isentropic efficiency of 85%, and the turbine an isentropic efficiency of 75%. if the temperature leaving the combustor and entering the turbine is 900°f, what is the quality of the steam leaving the turbine? what is the pump work and total heat addition, in btu/lbm? if the plant produces 100 mw of power, what is the mass flow rate of steam through the cycle (report your answer in lbm/min)?

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

connect the batteries in series and hope

i think the answer is a, hope this : )
