Ответ:
the stress is 384 pounds per square inch.
Step-by-step explanation:
Let S represent the stress in the material of the pipe.
Let P represent internal pressure of the pipe.
Let D represent internal diameter of the pipe.
Let T represent the thickness of the pipe.
The stress in the material of a pipe subject to internal pressure varies jointly with the internal pressure and the internal diameter of the pipe and inversely with the thickness of the pipe. Introducing a constant of proportionality, k, the expression becomes
S = kPD/T
The stress is 100 pounds per square inch when the diameter is 5 inches, the thickness is 0.75 inch, and the internal pressure is 25 pounds per square inch. It means that
100 = (k × 25 × 5)/0.75
125k = 100 × 0.75 = 75
k = 75/125 = 0.6
The equation representing the relationship becomes
S = 0.6PD/T
If the internal pressure is 40 pounds per square inch, the diameter is 8 inches and the thickness is 0.50 inch, then the stress would be
S = (0.6 × 40 × 8)/0.5
S = 384

waste water conversion to water that can be used for purposes other than drinking, is known as ‘waste water recycling’. in certain cases, where advanced technology is used, waste water is even converted to drinkable water, often referred to as ‘toilet to tap’ process.
water is thus converted into reusable water is used in agriculture, gardening, of automobiles and other structures and in ground water replenishment. where the degree of conversion is basic, it is most commonly used for of toilets.
a huge quantity of water can be saved by waste water conversion, where fresh water would have been used, otherwise.
summary: waste water conversion and usage of such water should be encouraged, to save precious fresh water, is these days, turning out to be a non-renewable resource.
