To solve this problem we will use the concepts given by the rotational kinetic energy which describes the energy in a body product of its moment of inertia and its angular velocity, mathematically this is given as,
Where,
I = Moment of Inertia
= Angular Velocity
Replacing with our values we have that,
Therefore the rotational energy is 178.125J
Answer:
The absolute pressure in the tank is 594 kPa.
Explanation:
Given that,
Gage pressure = 500 kPa
Atmospheric pressure = 94 kPa
Absolute pressure :
The absolute pressure is the addition of atmospheric pressure and gage pressure.
We need to calculate the absolute pressure in the tank
Using formula of absolute pressure
In mathematically form,
Put the value into the formula
Hence, The absolute pressure in the tank is 594 kPa.
