Answer:
heat flux ( Q ) = 8 W/m³ uniform heat flux throughout the block
Explanation:
flat plate ecuation with uniform source:
- d2T / dx² = - Q / k...........from general balance
- if x = 0 ⇒ dT / dx = 0 ; Q = 0
- if x = L ⇒ T = T1
∴ k = 0.04 W/mC; L = 0.2 m
If T = - 100x² + 20x
⇒ dT / dx = - 200x + 20
⇒ d2T / dx² = - 200 = - Q / k
⇒ Q / k = 200
⇒ Q = 200 * 0.04 W/mC
⇒ Q = 8 W/m³
Answer:
B. Mixture
because air,sea water and alloy are example of Mixture
Answer:
Explanation:
Amount HCl = 0.455mole
Molar mass = 1 + 35.5 = 36.5g/mol
Amount = mass/molar mass
:- mass = Amount × Molar mass
Mass = 16.97g
