How calculate rectangular water tank capacity in litters?
We assume the dimensions of water tank length, breadth and depth.
Take value in feet,
Length (L) = 12”
Breadth (B) = 8”
Depth (H) = 6”
To find volume of water tank,
Volume = L X B X
H
= 12 X 8 X 6
= 576 cu.ft
To find 1 cu.ft water?
Density of water = 1000 kg/cu.m
1 cu.m = 1000 liters (1000kgs)
1 cu.m
= 35.3198 cu.ft
water in 1 cu.ft
= 1000/ 35.3198
= 28.31 liters.
So, weight of water = 576 x 28.31
= 16306.56
~ 16307 liters. (16307 kgs)
The capacity of rectangular water tank is
16307
liters.
What is foundation? Functions of foundation and Types of foundation?
What is foundation?
The foundation of a building is that part of walls, piers and columns in
direct contact with the ground and transmitting loads to the ground. also
foundation known as substructure of the building.
Functions of foundation:
§ Evenly load Distribution of the structure
§ Reduction of load intensity
§ To prevent the lateral movement of supporting material
§ To increase stability of the structure
§ To safety against undermining
Types of foundation:
Foundations are classified in two types
Shallow foundation
Deep foundation
1. Shallow foundation
a.
Isolated footing
b.
Combined footing strap footing
c.
Grillage footing
d. Mat or raft footing
2. Deep foundation
a.
Piles foundation
b.
Cofferdams
c. Caissons foundation
What are the Types of steel Reinforcement?
Types of steel Reinforcement
There are mainly using three types of reinforcement
1.
REBARS
2.
WIRE REINFORCEMENT
3.
PRESTRESSING STEEL
1.REBARS:
It has two types plain reinforcement, deformed reinforcement
Plain reinforcement:
1.
Mild steel bars
2.
Carbon steel bars
3.
Low – Alloy steel bars
Deformed reinforcement:
1.
Mild steel ribbed bars
2.
HYSD bars
a.
CTD bars
b.
TMT bars
3.
Carbon steel bars
4.
Low – Alloy steel bars
5.
Stainless steel bars
6.
Rail and Axle steel bars
7.
Galvanized steel bars
8.
Low carbon chromium bars
9.
Epoxy coated bars
2.WIRE REINFORCEMENT:
1.
Hard – Drawn steel wire fabrics
2.
Plain and deformed welded wire fabrics
3.
Epoxy coated steel wire and welded wires
4.
Stainless – steel wire and welded wire
3.PRESTRESSING STEEL
1.
Medium tensile steel bar
2.
