- Calculated pressure drop in 16mm lateral of the fogging system
For first lateral :
ΔP = f×L/D×ρ/2×V²
where,
ΔP – pressure drop in lateral,
f – friction factor,
L – length of lateral,
D – diameter of lateral,
ρ – fluid density,
V – velocity
∴ ΔP = 0.0357×(16.5/16×10-3)×1/2×(04.17)²
= 10.2436/0.032
= 0.3201 KPa
= 0.03264 kg/cm²
For second lateral :
ΔP = f×L/D×ρ/2×V²
∴ ΔP = 0.0357×(14/16×10-3)×1/2×(4.17)²
= 8.6915/0.032
= 0.2716 KPa
= 0.02769 kg/cm²
For third lateral :
ΔP = f×L/D×ρ/2×V²
∴ ΔP = 0.0357×(16.5/16×10-3)×1/2×(4.17)²
= 10.2436/0.032
= 0.3201 KPa
= 0.03264 kg/cm²
25/09/2022
- Holiday.
26/09/2022
- Calculated velocity of water inside 2.5 inch PVC pipe and 16 mm lateral.
Flow rate of water in 2.5 inch pipe –
Q = 9000 LPH = 0.000252 m3/s
Cross-sectional area of pipe –
d = 0.0635 m
r = 0.03175 m
A = πr²
= 3.14×(0.03175)²
= 0.003165 m
Velocity of water in pipe –
Q = AV
∴ V = Q/A
= 0.00252/0.003165
= 0.7962 m/s
Cross-sectional area of 16 mm lateral –
d = 0.016 m
r = 0.008 m
A = πr²
= 3.14×(0.008)²
= 0.0002010 m²
Velocity of water in 16 mm lateral (3 laterals) –
Q = AV
∴ V = Q/A
= 0.00252/0.0002010
= 12.53 m²
Therefore, velocity in each lateral
V1 = V2 = V3 = V/3
= 12.53/3
= 4.17 m/s
27/09/2022
- There was a discussion session about design thinking.
28/09/2022
- Calculated flow rate (discharge) and velocity drop in 16 mm lateral of fogging system.
Discharge of one 4-way fogger –
30 LPH
Flow rate of water in 16 mm lateral –
Q = AV
= 0.0002010×4.17
= 0.0008382 m3/s
= 3006 LPH
Discharge at first fogger –
Q1 = Q – 30 LPH
= 3006 – 30
= 2976 LPH
= 0.0008267 m3/s
Discharge at second fogger –
Q2 = Q – 30 LPH
= 2976 – 30
= 2946 LPH
= 0.0008183 m3/s
Discharge at third fogger –
Q3 = Q – 30 LPH
= 2946 – 30
= 2916 LPH
= 0.0008100 m3/s
Discharge at fourth fogger –
Q4 = Q – 30 LPH
= 2916 – 30
= 2886 LPH
= 0.0008017 m3/s
Velocity drop in lateral when foggers are on –
V1 = A/Q1
= 0.0002010/0.0008267
= 0.243 m/s
V2 = A/Q2
= 0.0002010/0.0008183
= 0.246 m/s
V3 = A/Q3
= 0.0002010/0.0008100
= 0.248 m/s
V4 = A/Q4
= 0.0002010/0.0008017
= 0.251 m/s
Total velocity drop = V1 + V2 + V3 +V4
= 0.243 + 0.245 + 0.248 + 0.251
= 0.987 m/s

5/11/2022
Discussed about the systems which we have to install in BSF net for maintaining humidity and temperature.
Wick hydroponic system
This system consist of a reservoir i.e. any bucket or container that can hold enough water.
Several long strips of suitable wicking material, string or rope.
Some common household choices for a wick are :
- Nylon rope
- Wool rope / strip
- Braided PU yarn
- Propylene strips
- Mop head strings
- Strips from old clothes or blankets.
100 % cotton strip is very good for absorption and evaporation of water.
100% rayon doesn’t absorb water easily, but when it does absorb water, it holds on to it for a longer time.
50% polyester – 50% nylon , this blend of fabrics is very effective at absorbing water, but very ineffective at expelling it. Therefore, it holds on to its liquid contents for a long time.
100% polyester is neither good nor bad at retaining water.
Advantages :
- Cheap and easy setup.
- Minimal maintenance required.
