Milk enters a heat exchanger at 15°C and at a rate of 2000 kg/h. The heating medium is the latent heat provide by steam. The outlet temperature of the product is 95°C and the specific heat of the product is 3.9 kJ/(kg °C). If the latent heat provided by the steam is 2600 kJ/kg, estimate the flow rate of steam needed to accomplish product heating.

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
