A heat exchanger is used to cool spent steam from a turbine to capture its heat. It leaves the turbine at 120°C superheated steam and is cooled to 90°C liquid water. How much heat can be captured by the heat exchanger per
kg of spent steam? Work out using the information below. Box your answer. Be sure to include UNITS! Upload a

LHF=334 kJ/kg
LHV=2265 kJ/kg
ice cp=2.108 kJ/kg°C
water Cp=4.187kJ/kg°C
steam Cp=1.996 kJ/kg C

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
