Answer:
a) , b) , c)
Explanation:
a) The turbine is modelled by means of the First Principle of Thermodynamics. Changes in kinetic and potential energy are negligible.
The mass flow rate is:
According to property water tables, specific enthalpies and entropies are:
State 1 - Superheated steam
State 2s - Liquid-Vapor Mixture
The isentropic efficiency is given by the following expression:
The real specific enthalpy at outlet is:
State 2 - Superheated Vapor
The mass flow rate is:
b) The temperature at the turbine exit is:
c) The rate of entropy generation is determined by means of the Second Law of Thermodynamics:
Answer:
Float
Explanation:
The objects weight 14n and the buoyant force is 12n, so it will sink because the weight is greater than the buoyant force.
Equation: p = m/v
Answer:
equipment bonding jumper
Explanation:
A jumper is a small piece made of plastic that contains tiny metal filaments that are capable of conducting electricity. Through a series of jumpers, the conduction of electricity can be manipulated, being diverted to necessary places.
There are several types of jumpers. A jumper that provides connection between various equipment provides the connection between the conductor of the grounded circuit and the source-side connection jumper or the equipment's grounding conductor, or both, in a separately derived system.
Answer:
Potential energy can transfer into other forms of energy like kinetic energy. Kinetic energy is energy an object has because of its motion. ... If released, as the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy.
On a microscopic scale, conduction occurs as rapidly moving or vibrating atoms and molecules interact with neighboring particles, transferring some of their kinetic energy. Heat is transferred by conduction when adjacent atoms vibrate against one another, or as electrons move from one atom to another.
Momentum, p=mass* velocity
P=2250(25)
p=56250 kgm/s
