A parison is extruded from a die with outside diameter = 11.5 mm and inside diameter = 7.5 mm. The observed die swell = 1.25. Th
e parison is used to blow mold a beverage container whose outside diameter = 112 mm (a standard size 2-liter soda bottle). (a) What is the corresponding wall thickness of the container? (b) Obtain an empty 2-liter plastic soda bottle and (carefully) cut it across its diameter. Using a micrometer, measure the wall thickness to compare with your answer in (a).

Answer:
flow rate is 8.0385 × m³/s or 12.741 gpm
Explanation:
given data
12-nominal schedule 40 pipe
Reynolds number = 2000
to find out
What is the flow rate
solution
we know the diameter of 12-nominal schedule 40 pipe is
Diameter = 12.75 inch
D = 0.32385 m
and
dynamic viscosity of Turpentine is = 0.001375 Pa-s
and Density of Turpentine is 870 kg/m³
so
Reynolds number is express as
Re =
here ρ is density and D is diameter and V is velocity and µ is viscosity
so put here all value
2000 =
V = 9.7619 × m/s
and
flow rate is
Q = V × A
here A is area and Q is flow rate
Q = 9.7619 × ×
Q = 8.0385 × m³/s
so flow rate is 8.0385 × m³/s or 12.741 gpm

Answer:
Explanation:
Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise many, smaller units called photovoltaic cells. (Photovoltaic simply means they convert sunlight into electricity. The attached diagram give an ilustsration of the photovotaic pannel mounted on a roof top.
Solution
To Determine the electric power generated for
a) A still summer day.
E = A * r * H * PR
E = Total Amount of Energy in kilowatt
A = Total Surface Area
r = efficiency Rating
H = global radiation value
PR = Performance Ratio
kwh = watt * Time/1000
kwh = 100 * 35/1000
3.5
b)
kwh = watt * Time/1000
kwh = 30 *15/1000
4.5
