Calculate the rotational energy of a segment, given mass of the segment is 2.2 kg, moment of inertia is 0.57 kg-m2, and angular
Damm [24]

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,

KE = \frac{1}{2} I\omega^2

Where,

I = Moment of Inertia

\omega= Angular Velocity

Replacing with our values we have that,

KE = \frac{1}{2} (0.57)(25)^2

KE = 178.125J T

Therefore the rotational energy is 178.125J

A pressure gage connected to a tank reads 500 kPa at a location where the atmospheric pressure is 94 kPa. Determine the absolute
Leto [7]

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,

P_{abs}=P_{g}+P_{atm}

Put the value into the formula

P_{abs}=500 +94

P_{abs}=594\ kPa

Hence, The absolute pressure in the tank is 594 kPa.

It changes because radiation always differs in the atmosphere because of the nuclear plants and of pollution around us. Even though it is indoors.
