Dec 21, 2016 · As I said in the question, all I'm interested in is a rough rule of thumb – Zaid Aug 11 '16 at 14:38. 3. I was a Honda factory mechanic for years and we had a dyno at the shop. Yes, there is variance but not as much as you claim regarding, "all over the place."

Rule of Thumb; A 10% gradient is a typical safe haul road gradient in open pit mines for rigid body haul trucks The running surface of a two lane haul road should be ties the width of the largest truck operating on that road. A single lane road should be twice the width of the largest truck.

A simple rule of thumb is to take 100 sqft for every 1kW of solar panels. Extrapolating this, a 1 MW solar PV power plant should require about 100000 sqft (about acres, or 1 hectare). However, owing to the fact that large ground mounted solar PV farms require space for other accessories, the total land required for a 1 MW of solar PV power ...

As a rule of thumb, the energy requirement increases with fineness to the power, so the corresponding figure for a typical rapid hardening cement with specific surface 550 m².kg1, the corresponding data would be 66 kWh per tonne energy consumption and 152 tonnes per hour output.

As a rule of thumb. one may remember that every 22'C reduction in flue. gas temperature through the use of an econom zer or a. ... Proper control of coal fineness and excess air in.

The ruleofthumb design method provides information useful in power plant cycle optimization, including tower dimensions, water consumption rate, exit air temperature, power requirements and construction cost. In addition, a method for simulation of cooling tower performance at various operating conditions is presented.
