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.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

answer: an 8-foot rope is tied from the top of a pole to a

stake in the ground, as shown in the diagram

below

step-by-step explanation:

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
