1) tank 50 deep
2)discharge pump will empty tank at 250 gallons per minit
3)tank will at 100 gallons per minit
4)2-floats will contor (m1) to fill tank set at 25feet 42feet
5)a float is set at 10feet for shut off for discharge pump
6)install pressure switch to prevent discharge pump from running dry
7)install float for high level alarm at 45 feet
8)install float for low level alarm at 7feet this will also serve as backup shout off for the discharge pump
9)use master control relay to control circuit
10) use control relay to control low level alarm
11)low level alarm will be audible and controlled from master control relay
12)high level alarm will be audible alarm silence
It seems like you have provided a set of instructions or specifications for a tank system. To better understand your instructions, I will break them down and explain each point individually:
1) The tank is 50 feet deep.
To get the answer to this point, you simply provided the information without any need for calculation.
2) The discharge pump will empty the tank at a rate of 250 gallons per minute.
To calculate how long it will take to empty the tank, you would need to divide the total volume of the tank by the discharge rate. However, you haven't provided the volume of the tank, so you cannot determine the answer.
3) The tank will fill at a rate of 100 gallons per minute.
Similar to the previous point, without knowing the volume of the tank, you cannot determine how long it will take to fill the tank.
4) There are two floats (M1) to control the water level in the tank. One is set at 25 feet and the other at 42 feet.
This point doesn't require a calculation, but it specifies the two water level thresholds at which the floats will control the filling of the tank.
5) A float is set at 10 feet to shut off the discharge pump.
This point indicates that when the water level reaches 10 feet, the float will trigger the shut-off of the discharge pump.
6) A pressure switch is installed to prevent the discharge pump from running dry.
This point suggests that a pressure switch is included in the system to sense the fluid pressure and automatically shut off the discharge pump if the pressure drops too low, indicating the possibility of running dry.
7) A float is installed for a high-level alarm at 45 feet.
This point states that a float is set at 45 feet, and when the water level reaches this point, it will trigger a high-level alarm.
8) A float is installed for a low-level alarm at 7 feet. This float will also serve as a backup shut-off for the discharge pump.
This point indicates that a float is positioned at 7 feet, which will activate a low-level alarm when the water level drops to this point. Additionally, it will serve as a backup shut-off for the discharge pump.
9) A master control relay is used to control the circuit.
This point suggests that a master control relay is utilized to control the overall operation of the tank system, although further details on its function are not provided.
10) A control relay is used to control the low-level alarm.
This point indicates that a control relay is responsible for activating and controlling the low-level alarm when the water level reaches 7 feet.
11) The low-level alarm will be audible and controlled from the master control relay.
This point states that the low-level alarm will emit an audible sound when activated, and the control of this alarm will be managed by the master control relay.
12) The high-level alarm will be an audible alarm silence.
This point suggests that the high-level alarm will produce an audible alarm sound, but it can also be silenced, presumably by manually taking action.
Please note that while I have explained each point individually, some points lack specific information or calculations necessary to provide definitive answers. If you can provide more details or clarify any specific calculations you require, I can assist you further.
