Answer:
<em>The normal stress is 0.7821 MPa</em>
<em></em>
Explanation:
The external diameter D = 160 mm
The thickness t = 3.8 mm = 3.8 x 10^-3 m
gauge pressure P = 78 kPa = 78 x 10^3 Pa
The maximum shear stress τmax = ?
The external radius of the shell from the external surface R = D/2 = 160/2 = 80 mm
The internal radius of the shell r = R - t
==> 80 - 3.8 = 76.2 mm
Therefore the internal diameter d = 2r = 2 x 76.2 = 152.4 mm
==> d = 152.4 x 10^-3 m
The normal stress σ = = = 782052.63 Pa
==> σ = <em>0.7821 MPa</em>
The elevation difference between the PVC and the high point on the curve 0.1208 ft
<u>Explanation:</u>
g1 = 4.0%
= 0.04
The elevation of curve at a distance “x”from pvc is given by
x = distance from pvc to point on curve
The highest point on vertical curve is at a distance "x" is given by
so, elevation of highest point
here,
substitute above values in "y" equation,
Algebric sum of grades = A =
As per AASHTO,for V= 60 mph, K =151 based on Stopping sight distance
Minimum length of vertical curve
We know that,
solving above equation we get, elevation distance between highest point and pvc as 0.1208 ft
Answer:
The thickness of the oil reservoir is 10cm, the production rate of oil is 100m3, the well radius is 10cm, the permeability of the reservoir is 1um2, the porosity is 0.2, the viscosity of the oil is 4mPa.s, the density of oil is 850kg/m3. If the flow regime can be considered as linear flow, can this flow in the reservoir satisfy Darcy's
Answer:
Explanation:
Brooding can simply defined as. “Application of heat to the birds at early part of their life”. Brooding is the care of young chicks by provision of optimum environment. The temperature by external heat source provided until the chicks not become able to regulate its body temperature efficiently.09-May-2018
