ThermalThermal relief valve installed in a Hydraulic system will have the highest pressure setting.
<h3>What is the hydraulic system? What are the types of hydraulic systems ? </h3>
Hydraulic system function and perform tasks through using a fluid that is pressurized . There are two types of hydraulic systems open loop hydraulic systems and closed loop hydraulic system . In open loop ,when the actuating mechanism is idle ,there will be fluid flow but no pressure.
Closed loop system use an additional pump called charge pump or feed pump.
Thermal relief valve is Designed to protect the pump and operators in circumstances when the pump is running and the discharge outlets have been closed .

Answer: i really don't know bu i recomened you watch josie b asmr she is the best
Explanation:
Answer:


Explanation:
Wave 1, 
Wave 2, 
Wave 3, 
Wave 4, 
The general equation of travelling wave is given by :

The value of
will remain the same if we take phase difference into account.
For first wave,



For second wave,



For the third wave,



For the fourth wave,



It is clear from above calculations that waves 1 and 3 have same time period. Also, wave 2 and 4 have same time period. Hence, this is the required solution.
