Answer:
Amount of cleaning solution need for 1,200 square inches = 0.2 quart
Explanation:
Given:
Amount of cleaning solution need for 6,000 square inches = one quart
Find:
Amount of cleaning solution need for 1,200 square inches = one quart
Computation:
Amount of cleaning solution need for 1,200 square inches = one quart[1,200/6,000]
Amount of cleaning solution need for 1,200 square inches = 0.2 quart
C and A I think cause I don’t really remember this I done before it his to be C and A
Answer:
t = 6179.1 s = 102.9 min = 1.7 h
Explanation:
The energy provided by the resistance heater must be equal to the energy required to boil the water:
E = ΔQ
ηPt = mH
where.
η = efficiency = 84.5 % = 0.845
P = Power = 2.61 KW = 2610 W
t = time = ?
m = mass of water = 6.03 kg
H = Latent heat of vaporization of water = 2.26 x 10⁶ J/kg
Therefore,
(0.845)(2610 W)t = (6.03 kg)(2.26 x 10⁶ J/kg)
<u>t = 6179.1 s = 102.9 min = 1.7 h</u>
Answer:
,
Explanation:
The process is modelled after the First and Second Law of Thermodynamic:
The properties of the fluid are obtained from steam tables:
Inlet
Outlet
The heat transfer is:
Lastly, the entropy production is:
Use SAS(Side angle side ) rule.
Then cosine law i.e a^2=b^2+c^2-2*b*c*COSA
We will get a=69 mm
Now we have all sides use sine law
a/sinA=b/sinB
We will get B=60(deg)
And use the law: sum of all angles of triangle is 180(deg)
We will get C=75(deg).
