Career Pod

This episode I'm doing something a little different. These are some of my study notes from back when I was Pipefitting school.

The following numbers are the constants discussed in this podcast relevant to the pipe trades.

3.14 =Pi

4°C = water at most dense

39°F = water at most dense

0°C = freezing point of water

32°F = freezing point of water

7.5% = how much water expands when it freezes

100°C = boiling point of water

212°F = boiling point of water

1700 = times water expands volume from water to steam

2 kj/kg/°C = sensible heat of ice

0.5 btu/lb/°F = sensible heat of ice

335 kj/kg = latent heat required to change ice to water

144 btu/lb = latent heat required to change ice to water

4.2 kj/kg/°C = sensible heat of water

1 btu/lb/°F = sensible heat of water

2257 kj/kg = latent heat required to vaporize water to steam

970 btu/lb = latent heat required to vaporize water to steam

2 kj/kg/°C = sensible heat required to raise steam temperature

0.5 btu/lb/°F = sensible heat required to raise steam temperature

0.433 = psi per 1 foot head of water

0.0361 = psi per 1 inch head of water

2.31 ' = 1 psi

27.7 " = 1 psi

62.4 lbs = 1 cubic foot of water

10 lbs = 1 imperial gallon

6.24 = imperial gallons in a cubic foot

0.833 imperial gallons = 1 US gallon

1.2 US gallon = 1 imperial gallon

150 btu per EDR of water

240 btu per EDR of steam

121°C = max temperature of low pressure boiler

250°F = max temperature of low pressure boiler

15 psi = max working pressure of low pressure boiler

33, 475 btu = one boiler horsepower

34.5 lbs of water into steam @ 212°F/100°C = 1 BHP

(°F - 32) / 1.8 = °C

(°C x 1.8) + 32 = °F

2.54 cm = 1 inch

25.4 mm = 1 inch

2.2 lbs = 1 kg

0.24 btu/lb/°f = specific heat capacity of air

1 = relative density of water and air

13.6 = relative density of mercury

0.076 lb = weight of 1 cubic foot of air @STP

14.7 psi = atmospheric pressure @ sea level

29.92" mercury = one atmosphere

760 mm = one atmosphere

30° = angle used on isometric drawings

Best of luck in your journey studying!

Join me as my neuro-divergently beautiful brain tries to waffle through a summary of why I started the podcast 7 years ago and how I'm ready to dive back in; okay maybe test the waters...who am I kidding, I secretly love audio editing and chatting with people way more interesting than myself—qué hermosa vida!
