Answer:
Geologist is your answer. Hope it helps you. Please mark me as the brainliest.
Explanation:
They study the materials of the Earth and the wild processes upon it. Their wider understanding of the Earth and its processes is also important, not just for the rocks. Geologists may be experts on mudslides and other ground-based natural disasters and what cause them, earthquakes and volcanoes for example.
Answer: Nixon planned to officially resign at noon on the day following his speech.
Answer:
A) Mean Temperature = 287.80K
B) Mean Temperature = 300.78K
Explanation:
D = 0.05m
T = 285K
M = 0.25kg/s
h = K
CP = 4180 j/kg k
<u>Part A) Pipe Heated Uniformly</u>
Ф =
L = 5m
Ф = m cp [T2 - T1]/A
AФ = 0.25 * 4180 [T2 - 285]
5600 * π * dL = 0.25 * 4180 [T2 - 285]
5600 * π * 0.05 * 5 = 0.25 * 4180 [T2 - 285]
T2 = 289.20
TM =
TM =
TM = 287.1 K
Part B) Pipe Maintained at 320K
Ф = hA [Ts - T1]
Ф = 1200 * π * 0.05* 5 [320 -285]
Ф = 32986.72 watt'
Ф = mcp [T2 - T1]
32986.72 = 0.25 * 4180 [T2 - 285]
T2 = 316.56K
TM =
TM =
TM = 300.78 K
