Answer:
The answer 30.07J/sec
Explanation:
GIVEN DATA:
temperature of steam = 40 degree celcius
mass flow rate = 63 kg/h
from saturated water tables,
from temperature 40 °, enthalpy of evaporation value is 2406 kj/kg
rate of heat transfer (Q) can be determine by using following relation
putting all value to get Q value
Q = 45 *2406
Q = 108270 kJ/h
Q = 30.07 kJ/sec
Answer:
to be or not to be

Answer:
Explanation:
The pictures below shows the whole explanation for the problem
Student A is accurate and Student B is precise.
<u>Explanation:</u>
Accuracy is nothing but how close a measured value is to its standard value. Precision means how closer two or more than two measurements are to one another, despite whether those values are accurate or not.
In Student A's measurement, 10.11 ml, 10.04 ml and 9.97 ml are closer to the standard value, so they are accurate.
Student B's value 9.45 and 9.5 are closer to one another, so it is precise.
