Ques:- How to calculate cement and sand quantities in cement mortarAs 1:1,1:2,1:4,1:6 ?
Asked In :- ASME, volvo trucks, fmg ltd,
Right Answer:
To calculate cement and sand quantities in cement mortar for mixes 1:1, 1:2, 1:4, and 1:6, follow these steps:

1. Determine the total volume of mortar required (in cubic meters).
2. Use the formula:
- For 1:1 mix: Total Volume = 1 part cement + 1 part sand
- For 1:2 mix: Total Volume = 1 part cement + 2 parts sand
- For 1:4 mix: Total Volume = 1 part cement + 4 parts sand
- For 1:6 mix: Total Volume = 1 part cement + 6 parts sand

3. Calculate the total parts:
- 1:1 = 2 parts
- 1:2 = 3 parts
- 1:4 = 5 parts
- 1:6 = 7 parts

4. Calculate the
Ques:- What is the basic principal of vertax flow meter
Right Answer:
The basic principle of a vortex flow meter is based on the creation of vortices when a fluid flows past a bluff body. The frequency of the vortices generated is proportional to the flow rate of the fluid, allowing for accurate measurement of the flow.
Ques:- Can u explain about design patterns likesingleton,builder,factory
Asked In :-
Right Answer:
**Singleton**: A design pattern that ensures a class has only one instance and provides a global point of access to it.

**Builder**: A design pattern that allows for the step-by-step construction of complex objects, separating the construction process from the representation.

**Factory**: A design pattern that provides an interface for creating objects in a superclass but allows subclasses to alter the type of objects that will be created.

Ques:- Why compression strenth of concrete is tested with a cube of size 150x150x150 mm ?
Right Answer:
The compression strength of concrete is tested with a cube of size 150x150x150 mm because this size is standardized in many testing codes, providing a consistent and reliable measure of concrete's strength properties.
Ques:- What will be the velosity of a water at in the pipe of 6 inches which is situated at the bottom of 10 mtr tank ?
Right Answer:
The velocity of water at the bottom of a 10-meter tank can be calculated using Torricelli's law:

[ v = sqrt{2gh} ]

Where:
- ( g ) (acceleration due to gravity) = 9.81 m/s²
- ( h ) (height of the water column) = 10 m

Calculating:

[ v = sqrt{2 times 9.81 times 10} approx 14.14 , text{m/s} ]

So, the velocity of water at the bottom of the tank is approximately **14.14 m/s**.

Asked In :-
Ques:- why stirrups are provided at 0.3l at supports and 0.4l at center?
Asked In :- tata steel, rohde & schwarz,
Right Answer:
Stirrups are provided at 0.3l at supports to resist shear forces and prevent diagonal tension failure, while at 0.4l at the center, they help control cracking and provide additional support where bending moments are highest.
