Answer:
10500 J/kg/*C
Explanation:
Quantity of heat required=mass of substance x specific heat capacity x change in temperature
Quantity of heat required=0.25 x 4200 x [30-20]
Quantity of heat required=0.25 x 4200 x 10
Quantity of heat required=10500 J/kg/*C
“Yes, it is impossible to go around the curved path with zero acceleration. Acceleration is change in velocity. And velocity( speed+ direction) changes at every point in a curved path because there is change in direction at every point.”
Answer:
mass flow rate = 11.464 kg/sec
Explanation:
given data
P = 200 kPa = 2 ×
Pa
temperature = 150°C = 423 k
volumetric flow rate = 7000 liters/s
solution
first we get here molar flow rate that is express as
molar flow rate =
.................1
put here value
molar flow rate =
molar flow rate = 398.06 mol/sec
and
now we get mass flow rate
mass flow rate = molar flow rate × average mol weight ..............2
mass flow rate = 398.06 × 28.8
mass flow rate = 11464.3 g/sec
mass flow rate = 11.464 kg/sec
Answer:
<em>Fundamental units are the units of the fundamental physical quantities in SI system. They are not formed from other units. There are a total of seven fundamental units such as meter, kilogram, ampere, and second. Derived units are those units that are used for derived quanti</em>ties.
