DISCLAIMER: Remember all of the following are just general guidelines and should not be relied on as a precise source for information.

Key points to remember:

• Pressure loss: As fluid flows through a pipe, it experiences pressure loss due to friction. Longer pipes and higher flow rates generally lead to greater pressure loss.
• Noise: High flow velocities can cause noise in pipes. Minimizing noise often involves using larger pipes or reducing flow rates.
• Safety: Exceeding the pressure rating of a pipe can be dangerous. Always consult with a qualified professional if you're unsure about the safe operating pressures for your piping system.
  
  
  

1. You should size your pipe so that your flow velocity stays in the green or yellow range.
2. The green range is safest, most efficient and will produce little to no noise. 
3. Flow velocities in the yellow range may be noisy and have additional back pressure. 
4. Flow velocities in red are not recommended because of the risk of hydraulic shock and pipe/fitting/joint & pump failure.
5. Find your flow in the first column (GPM) and then select the pipe size you want in the second column (pipe, ID in inches.) 
6. Draw a straight line between them all the way to the last column. If the line ends up in the green you are good. If it ends in the yellow or red, increase the pipe size until your line ends in the green (best) or yellow (just okay) area.
   

1. The display is downgraded to an ergonomic 4.7inch 720p display (has the same ppi as an Iphone).
2. The battery capacity is increased to 5000mah.
3. An increase of 20% in the overall hardware operating efficiency is applied:
   A.) As per regular technological advances in 2 years which has already been achieved in the latest series of Snapdragon hardware, and
   B.) As per the decrease in processing of screen elements due to the display bein down-scaled to 60% (720p) of its original resolution (1080p).
4. No increase in overall software operating efficiency is assumed as any increase in efficiency gets used by the increase in processing load as software evolves to be heavier with time.

1. The new screen on time will be:
   15*(1080/720)*(5000/3510)*1.2=~38.5 hours.
   This is equivalent to 5.5 hours of screen on time for all 7 days of the week!
2. But for most *average* users, the average daily SOT is 4 hours.
3. So we have an extra SOT of [38.5 hours - (4 hours*7 days)]=10.5 hours on our hands (remember this number it will come in handy later)
4. Additionally, the doze/sleep mode time is increased to:
   19 hours*3*(5000/3510)*1.2=~97.5 hours.
5. However, our desired doze/sleep mode time is 20 hours*7=140 hours
   Thus it can be seen that our doze/sleep mode time is short by (140 hours - 97.5 hours)=42.5 hours
6. This shortcoming can be achieved by now using the extra 10.46 hours of SOT we have on our hands.
   Since we already know that 1 hour of SOT equals 3.8 hours of sleep/doze,
   10.5 hours of SOT =~40 hours.
7. Thus the doze/sleep mode time is further increased to: 97.5 hours+40 hours= 137.5 hours (this is 2,5 hours short of the desired 140 hours).

1. 28 hours of screen on time = 4 hours*7 days
2. 137.5 hours (2.5 hours short of the required 140 hours) of doze (sleep with sync) time
3. 6.895 days of battery life (1.5% short of the required 7 days)
   
   

1. 4 hours of SOT.
2. 20% increase in total hardware efficiency.
3. I only used Wi-Fi for internet and not an LTE connection.
4. I didn't play any games or poorly coded apps (like Facebook's official app).
5. Weight of phone - the weight of your phone will actually stay the same as we are ditching at least ~20% of the weight of the phone by making its screen smaller thus resulting in lesser size (thus weight) of components being used. This decrease in weight of the phone's body will be balanced by the increase in the weight of the battery by ~30%.
