Answer:
The answer is <em>False</em>.
Explanation:
Type 1 ladders have a duty rating of 250-pounds. The fact that the person is carrying a load means that they are exceeding 250 pounds.
Type 1A would be best.
In other words, it's better to be safe than sorry.

d. 185
Explanation:
Spheriodite is microscopic constituents in some steels which is composed of spherically shaped cementide particle. It is most ductile and softest type of steel. Pearlite is two phased lamellar compose of alternating layer of ferrite and cementite. It is hard and strong but not tough. It is applied on cutting tools like chopper, blades and knives.
Answer:
Heat generation per unit volume is 45 KW.
Explanation:
Given that
Thickness of wall = 6 cm
Temperature distribution
-----1
K= 15 W/m.k
As we know that at steady state condition
-----2
Where q is the heat generation per unit volume.
So from equation 1


Now from equation 2
So q= 45 KW
So heat generation per unit volume is 45 KW.
Answer:
hello some data related to your question is missing attached below is the missing data
answer : 63700 Ib/hr
Explanation:
Given data :
Limestone mix : consists of 94% CaCO3 and 6% inert material
Actual feed rate = 36,000 Ib/hr
SO2 in flue gas = 20,314 Ib/hr
FGD efficiency = 97%
resulting sludge contains 58% solids
<u>Calculate the Total sludge production rate </u>
First : determine SO2 removed in sludge
= 0.97 * 20314
= 19704.58 Ib/hr
next : moles of SO2 removed
= 19704.58 / 64 Ib/ Ib mol
= 307.88 Ib mol / hr
also moles of CaSO3 produced = 307.88 Ib mol / hr
mass of CaSO3 = 307.88 * 120 = 36946.09 Ib/hr
Therefore Total sludge production rate
= 36946.09 / 0.58
= 63700.15 Ib/hr
