Explanation:
a) The Reynolds number for the water flowing in a circular tube is:
Let assume that density and dynamic viscosity at 25 °C are
, respectively. Then:
b) The result is:
The 1-hour standard for NO2 from the NAAQS is 100 ppb NO2. Each breath you take is approximately 1 L of air. Assuming the air yo
u breathe is at the 1 hour standard limit for NO2: a. How many grams of NO2 do you take in with each breath? b. How many molecules of NO2 do you take in with each breath? Use formula found in the front cover of APCE to convert: (assume the air is 25 C and 1 atm) lppm - MWmolecuie)lg /m3.

Answer:
correct option is (A) 0.5
Explanation:
given data
axial column load = 250 kN per meter
footing placed = 0.5 m
cohesion = 25 kPa
internal friction angle = 5°
solution
we know angle of internal friction is 5° that is near to 0°
so it means the soil is almost cohesive soil.
and for a pure cohesive soil
= 0
and we know formula for is
= (Nq - 1 ) × tan(Ф) ..................1
so here Ф is very less should be nearest to zero
and its value can be 0.5
so correct option is (A) 0.5
Answer:
Tmax=14.5MPa
Tmin=10.3MPa
Explanation:
T = 600 * 0.15 = 90N.m
=14.5MPa
=10.3MPa
