Rational Method Runoff Coefficients One of the parameters in the Rational Method equation ( Q = CiA ) is the runoff coefficient C The other parameters are A the area of a watershed i the design rainfall intensity for a storm of specified recurrence interval and duration equal to the watershed time of concentration and Q the peak storm water runoff rate due to a storm of intensity i on
In order to ensure the expected size of the parts after final bending by the press brake the design of sheet metal parts will use a variety of algorithms to calculate the actual length of sheet metal under folding status One of the most commonly used methods is the simple "pinch rules" that is based on their own experience in the algorithm
Fig 8 shows the optimum composition of the make-up ball sizes for various feed sizes as a function of the size reduction ratio R Because mixtures of two balls (50 8 mm and 25 4 mm ball) are always found to be optimum the results are plotted with the ordinate being the fraction of 50 8 mm balls
10/3/2013The pore size distribution of the aggregate may be measured using a mercury porosimeter The pore size (D50) when the accumulated volume percentage of the pore size distribution of the aggregate is 50% is preferably 0 1 to 0 2 μm Here the reason why D50 of the pore size distribution of the aggregate is limited is as follows
Basic pump components such as the impeller size and design material of construction and discharge configurations must be considered to ensure the pump will hold up against the wear caused by an abrasive slurry Slurry pumps are generally larger in size when compared to low-viscosity liquid pumps and usually require more horsepower to operate
Welcome to Toshiba's India website This website provides Information about Toshiba Toshiba Group aims to become an even stronger global contender by unleashing our powers of imagination to anticipate ahead of others and capitalize on the coming trends in the world business environment
Mill Type Overview Three types of mill design are common The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges
