Engine List 1 - Atomic Rockets

Apr 03, 2021 · The equations for delta V and mass ratio are slightly different for a Solar Moth or Laser Thermal rocket engine: Δ v = sqrt((2 * Bp * Bε) / mDot) * ln[R]. R = e (Δ v /sqrt((2 * Bp * Bε) / mDot). where. Δ v = ship's total deltaV capability (m/s); R = ship's mass ratio; Bp = Beam power (watts) of either laser beam or solar energy collected; Bε = efficiency with which engine converts beam

Is it cheaper to heat my home with gas or electricity

Jun 07, 2018 · Of course, your lpg boiler will not be efficient, but it will work out significantly cheaper than an electric boiler, at 15p/kWh. You could look at combining an electric system with solar PV and/or solar thermal, which would mean you would use far less mains electricity, but for a straight swap you are better sticking with your LPG for now.

Understanding Steering Gear in Ships

Dec 04, 2020 · We are all familiar with the use of a rudder, which helps in turning a ship as and when required.Rudders are the principal system for the entire motion and control of the ships. But we mustn't forget that the entire rudder action is dependent on another pivotal system called the Steering Gear. Steering Gear integrated with the rudder system defines the complete 'turning mechanism

Thermal expansion rate of water: Hot Water Expansion Rate

The heating boiler temperature and pressure given above are conditions much hotter than we should ever see in a domestic water heater tank where to avoid scalding hazards we limit water to about 100°F to 120°F but it is certainly possible to set water heaters to higher temperatures (and thus potentially higher pressures).
