Final Temperature in Heating Applesauce. A mixture of 454 kg of applesauce at 10°C is heated in a heat exchanger by adding 12130
jok3333 [9.3K]

Answer:

T_f = 76.46°C

Explanation:

Given data:

Mass of mixture = 454 kg

Initial temperature is 10°C

Heat added is Q = 121300 kJ

Heat capacity (Applesuace) at 32.8°C is 4.02kJ/kg K

From heat equation we have

Q = mCp(T_f -T_i)

\frac{Q}{mCp} = (T_f -T_i)

T_f = T_i + \frac{Q}{mCp}

Putting all value to get required final temperature value

T_f = \frac{121300}{454\times 4.02} + 10

T_f = 76.46°C

Round 23.455 cm into 4 significant figures
seraphim [82]
It would be 23.46, since the next number is a 5 so we can round up.

Significant figures are:
ANY number that is not 0
Any 0 between two nonzero digits
Any 0 following a decimal (i.e 1.50)
