Referred to as Carrier Frequency
Answer and Explanation:
Maintenance Job activity is of great importance for any firm or organization as it is the deciding factor of the firm's smooth functioning of a number of operations in the firm.
This requires the consideration of various factors prior to the maintenance activity which are as follows:
1. Planning:
Proper planning must be done in order to avoid risks and how to effectively control and mitigate risks related to the workplace, personnel, equipment, material, etc and to ensure proper maintenance of the firm and it's resources.
2. Allocation of appropriate tools and equipment:
In order to ensure proper maintenance, appropriate tools and equipment should be allocated to the workers to carry out their tasks properly and to ensure the structural safety and stability.
Some of these includes equipment for protection of personnel, safety ladders, etc.
3. Safe working environment:
Ensuring the safety of the work area by taking proper safety measures like protection against machine faults thus preventing accidents, protection against the unauthorized access and entry in the working area, taking care of power supply and proper power discharges and maintaining clean and hygienic atmosphere for the safe mobility of the material and personnel.
Answer:
car’s thermostat is used to regulate the temperature of the engine to help the engine stay cool.
Explanation:
Answer:
12.332 KW
The positive sign indicates work done by the system ( Turbine )
Explanation:
Stagnation pressure( P1 ) = 900 kPa
Stagnation temperature ( T1 ) = 658K
Expanded stagnation pressure ( P2 ) = 100 kPa
Expansion process is Isentropic, also assume steady state condition
mass flow rate ( m ) = 0.04 kg/s
<u>Calculate the Turbine power </u>
Assuming a steady state condition
( p1 / p2 )^(r-1/r) = ( T1 / T2 )
= (900 / 100)^(1.4-1/1.4) = ( 658 / T2 )
= ( 9 )^0.285 = 658 / T2
∴ T2 = 351.22 K
Finally Turbine Power / power developed can be calculated as
Wt = mCp ( T1 - T2 )
= 0.04 * 1.005 ( 658 - 351.22 )
= 12.332 KW
The positive sign indicates work done by the system ( Turbine )
