Answer:
t = 5.55 mm
Explanation:
given,
Gauge pressure (P)=640 kpa
Allowable normal stress =150 Mpa.
Inner diameter of tank =2.6 m.
Minimum thickness of wall. = ?
In case of closed cylinders there are two cases.
one is Circumferential stress and another one is longitudinal stress.
According to circumferential stress
Where
p=pressure, d=diameter, t= thickness,
by substituting all values we get,
t = 5.55 mm
minimum thickness of the wall is equal to t = 5.55 mm
Answer:
Europium has a bright shiny surface. it's steel grey and has a melting point of 826 degree Celsius and a boiling point of about 1,489 degree Celsius.
