**Three pipes A, B and C can fill a tank from empty to full in 30 minutes, 20 minutes, and 10 minutes respectively. When the tank is empty, all the three pipes are opened. A, B and C discharge chemical solutions P, Q and R respectively. What is the proportion of the solution R in the liquid in the tank after 3 minutes?**

__Question 1.__- $$\frac{5}{{11}}$$
- $$\frac{6}{{11}}$$
- $$\frac{7}{{11}}$$
- $$\frac{8}{{11}}$$

**Answer: Option B**

**Pipes A and B can fill a tank in 5 and 6 hours respectively. Pipe C can empty it in 12 hours. If all the three pipes are opened together, then the tank will be filled in:**

__Question 2.__- $$1\frac{{13}}{{17}}$$ hours
- $$2\frac{8}{{11}}$$ hours
- $$3\frac{9}{{17}}$$ hours
- $$4\frac{1}{2}$$ hours

**Answer: Option C**

**A tank is filled by three pipes with uniform flow. The first two pipes operating simultaneously fill the tank in the same time during which the tank is filled by the third pipe alone. The second pipe fills the tank 5 hours faster than the first pipe and 4 hours slower than the third pipe. The time required by the first pipe is:**

__Question 4.__- 6 hours
- 10 hours
- 15 hours
- 30 hours

**Answer: Option C**

**A large tanker can be filled by two pipes A and B in 60 minutes and 40 minutes respectively. How many minutes will it take to fill the tanker from empty state if B is used for half the time and A and B fill it together for the other half?**

__Question 12.__- 15 minutes
- 20 minutes
- 27.5 minutes
- 30 minutes

**Answer: Option D**

**Water is continuously supplied from a reservoir to a locality at the steady rate of 10000 liters per hours. When delivery exceeds demand the excess water is stored in a tank. If the demand for 8 consecutive three hour periods is 10000, 10000, 45000, 25000, 40000, 15000, 60000 and 35000 liters respectively, what will be the minimum capacity required of the water tank (in thousand liters)to meet the demand and avoid any wastage?**

__Question 16.__- 10
- 30
- 40
- 50

**Answer: Option C**

### How Do You Calculate Volume Of A Tank?

To find the capacity of a rectangular or square tank: Multiply length (L) by width (W) to get area (A). Multiply area by height (H) to get volume (V). Multiply volume by 7.48 gallons per cubic foot to get capacity (C).

### What Are Basilar Cisterns?

The subarachnoid cisterns, or basal cisterns, are compartments within the subarachnoid space where the pia mater and arachnoid membrane are not in close approximation and cerebrospinal fluid (CSF) forms pools or cisterns (Latin: "box"). As they are interconnected, their patency is essential for CSF circulation.

### What Is A Inlet And Outlet?

The difference between inlet and outlet:

Is that inlet is a body of water let into a coast, such as a bay, cove, fjord or estuary while outlet is a vent or similar passage to allow the escape of something.

### What Is Cistern Tank?

Water storage tanks, also known as cisterns, are primarily used to store water for domestic and consumptive purposes in households or buildings. Cisterns are typically found in areas where a potable. water source is not available in the community, the area. yields low well water capacity, or the groundwater quality.

### What Is The Volume Of Cistern?

We have a cistern to hold spring water that measures 12 feet in depth by 5 feet in diameter. How much in liquid gallons will it hold? Ï€ Ã— 302 Ã— 144 = 407,150.40 cubic inches. 407,150.40/231 = 1,762.6 US gallons.

### What's The Purpose Of A Cistern?

Cisterns are large tanks that store rainwater collected from impervious surfaces for domestic uses or for consumption.

### Why Inlet Pipe Is Provided With Screen?

The ponds that are supplied by rain, surface runoff and groundwater does not require inlet structures. The inlet should have a screen because it prevents wild fish, trash and dirt from entering when pond is being filled.

### How Do Cisterns Work?

Water enters a cistern from an external source such as rainwater from a rooftop, pumped water from a spring or other supply, or even by delivery by water truck. Water from a cistern is typically pumped out by hand, drained by gravity, or it may be pumped by an electric pump such as a one line jet pump.

### How Do You Calculate The Capacity Of A Pipe And Cistern Tank?

Let the capacity of the tank = LCM of (12,15, 6) = 60 litres. If all the pipes are opened simultaneously, (5+4-10) litres will be filled in a minute.

### What Are Cisterns Class 9?

A reservoir or a closed space filled with body fluid like chyle, lymph, or cerebrospinal fluid etc is called cistern.

### What Is Pipe And Types In Angular?

Types of Pipe:

In Angular 8, we can categories the pipes in two types i.e. Pure Pipes and Impure Pipes. Pure Pipes:- Pure pipes in angular are those pipes which always accepts some arguments as input value and return some value as the output according to the input values.

### What Is The Capacity Of Cistern?

A 4 liter cistern is one of the features of most modern toilets. This is supposed to save water.

### How Do You Solve A Pipe Question?

Steps to Solve Pipes and Cistern with Trick:

- Take the LCM of a given Number and that LCM will be the total capacity of cistern or. tank.
- Add or Subtract According to a particular question.
- The LCM from Step 1. will be the total work . Divide the total capacity of cistern or tank with the outcome of Step 2.

### How Many Litres Does A Cistern Hold?

Conventional cisterns hold between 4.5 and 6 litres, but the Encore holds 18 litres.

### How Do You Calculate Tank Capacity Of Pipes And Cisterns?

If two pipes take x and y hours respectively to fill a tank of water and a third pipe is opened which takes z hours to empty the tank, then the time taken to fill the tank = {1 / (1/x)+(1/y)+(1/z)} and the net part of the tank filled in 1 hr = (1/x)+(1/y)-(1/z)

### How Do You Solve A Pipe And Cistern Problem?

- Illustration 1: If a pipe fills a tank in 20 minutes and a pipe empties the same tank in 60 minutes.
- Sol: Let the tank be filled in X minutes.
- Illustration 2: Two pipes fill a tank in 20 minutes and 60 minutes.
- Sol: Let the tank is filled in X minutes.
- Illustration 3:
- Solution:
