A fire nozzle is coupled to the end of a hose with inside diameter D = 77 mm. The nozzle is smoothly contoured and its outlet di
ameter is d = 33 mm. The nozzle is designed to operate at an inlet water pressure of 744 kPa (gage). (a) Determine the design flow rate of the nozzle. (Express your answer in L/s.) (b) Evaluate the axial force required to hold the nozzle in place. (c) Indicate whether the hose coupling is in tension or compression.
1 answer:
Answer:
Explanation:
Axial Force is normally referred to as the Force acting along the path of the module or assembly. For instance, let’s consider a cylindrical Square column or Building column. Now the column is a structural part of the whole structure and it is planned and designed to take Axial Compression force.

Answer:
ΔQ = 4930.37 BTu
Explanation:
given data
height h = 8ft
Δt = 8 hours
length L = 24 feet
R value = 16.2 hr⋅°F⋅ft² /Btu
inside temperature t1 = 68°F
outside temperature t2 = 16°F
to find out
number of Btu conducted
solution
we get here number of Btu conducted by this expression that s
......................1
here A is area that is = h × L = 8 × 24 = 1492 ft²
put here value we get
solve it we get
ΔQ = 4930.37 BTu
