Answer:
5.6 mm
Explanation:
Given that:
A cylindrical tank is required to contain a:
Gage Pressure P = 560 kPa
Allowable normal stress = 150 MPa = 150000 Kpa.
The inner diameter of the tank = 3 m
In a closed cylinder there exist both the circumferential stress and the longitudinal stress.
Circumferential stress
Making thickness t the subject; we have
t = 0.0056 m
t = 5.6 mm
For longitudinal stress.
t = 0.0028 mm
t = 2.8 mm
From the above circumferential stress and longitudinal stress; the stress with the higher value will be considered ; which is circumferential stress and it's minimum value with the maximum thickness = 5.6 mm
Explanation:

Answer:
Consumers not having a can opener readily available
Explanation:
More people will be likely to buy a product that is easy to use. For example, yogurt cups have pull tabs in order to open the yogurt without leaving any cover attached. Ease of use is one of the key main design constraints when designing consumer goods.
Answer:
COP of refrigerator is the ratio of refrigerating effect or heat extraction from the refrigerator space to the work input.
Explanation:
Step1
COP stands for coefficient of performance of the heat pump or refrigerator depending upon working device. COP of refrigerator is the ratio of refrigerating effect or heat extraction from the refrigerator space to the work input. Refrigerating effect is the cooling effect of the refrigerator.
Step2
Expression for COP of refrigerator is expressed as follows:
Step3
COP of the refrigerator directly indicates the cost of refrigerator or the cooling effect as compare to work input or energy input by compressor.
The diagram of the refrigerator is shown below.
