Design a PLC ladder logic program to control the operation of a conveyor-storage system using the following sequence: - 1. Progr

am a count-up to keep track of the parts brought into the storage room by the CONVEYOR_IN and detected with a PROXIMITY_IN sensor.
2. Program a count-down to keep track of the parts taken out of the storage room by the CONVEYOR_OUT and detected with a PROXIMITY_OUT sensor.
3. Both conveyor motors are operated by one START/STOP seal-in pushbutton station.
4. A GREEN light must be on if the part count in the storage room is equal to zero (0).
5. A YELLOW light must be on if the part count in the storage room is between one (1) and ten (10) (inclusive).
6. A RED light must flash on and off in periods of 0.5 seconds if the part count in the storage room is greater than ten (10).
7. A RESET pushbutton is used to reset the count. - Program CONVEYOR_IN and CONVEYOR_OUT using bits 0 and 1 of the output module.
8. Program the GREEN, YELLOW, and RED lights using bits 2, 3, and 4 of the output module.
9. Program the START and STOP buttons as normally open in bits 0 and 1 of the input module.
10. Program PROXIMITY_IN and PROXIMITY_OUT using bits 2 and 3 of the input module.
11. Program the RESET pushbutton using bit 4 of the input module.

A pipe is insulated such that the outer radius of the insulation is less than the critical radius. Now the insulation is taken o
irina [24]

Answer:

the heat transfer from the pipe will decrease when the insulation is taken off for r₂< r_{cr}

where;

r₂ = outer radius

r_{cr} = critical radius

Explanation:

Note that the critical radius of insulation depends on the thermal conductivity of the insulation k and the external convection heat transfer coefficient h .

r_{cr} =\frac{k}{h}

The rate of heat transfer from the cylinder increases with the addition of insulation for outer radius less than  critical radius (r₂< r_{cr}) 0,  and reaches a maximum when r₂ = r_{cr}, and starts to decrease for r₂< r_{cr}. Thus, insulating the pipe may actually increase the rate of heat transfer from the pipe instead of decreasing it when r₂< r_{cr} .

If the price of the car is less than or equal to your available cash, display "no". If the price of the car is more than your av
Ede4ka [16]

Answer:

function decision(car_price, available_cash) {

   if(car_price <= available_cash) {

   console.log("no");

   }

   else  {

   console.log("yes");

   }

   }

decision(car_price, available_cash); or decision(available_cash, car_price);

Explanation:

using functions in Javascript:

functions; this refers to dividing codes into reusable parts.

e.g function function_name() {

console.log("How are you?");

}

you can call or invoke this function by using its name followed by parenthesis, like this: function_name(). each time the function is called it will   print out "How are you?".

Parameters: these are variables that act as placeholders for the values that are to be input into a function when it is called

Arguments: The actual values that input or passed into a function when it is called.

e.g

function function_name(parameter1, parameter2) {

console.log(parameter1, parameter2);

}

then we call function_name: function_name("please", "leave"):we have passed two arguments, "please"  and "leave". Inside the function parameter1 equals "please" while parameter2 equals "leave".

Hence, from the question given the two parameters "car_price" and "available_cash" respectively, we write the function with name function_name:

function decision(car_price, available_cash) {

   if(car_price <= available_cash) {

   console.log("no");

   }

   else  {

   console.log("yes");

   }

   }

decision(car_price, available_cash); or decision(available_cash, car_price);

13 Which pump is the most appropriate for low head high discharge capacity installations?
gavmur [86]

Options are missing and they are;

A. Propeller pump

B. Jet (mixed flow) pump

C. Centrifugal pump

D. Positive displacement pump

Answer:

C. Centrifugal pump

Explanation:

Dynamic pumps which are also known as centrifugal pumps are the ones widely used when we require high discharge. This is because they deal with transfer of fluids with low viscosity in flow rates that are high. Another reason is that they are also very good with low pressure installation.
