A year loss table (YLT) is a table that lists historical or simulated years, with financial losses for each year. [ 1 ] [ 2 ] [ 3 ] YLTs are widely used in catastrophe modeling as a way to record and communicate historical or simulated losses from catastrophes.
After both minor losses and friction losses have been calculated, these values can be summed to find the total head loss. Equation for total head loss, , can be simplified and rewritten as: = [() + (,)] [5] = Frictional head loss = Downstream velocity = Gravity of Earth
The following table gives flow rate Q such that friction loss per unit length Δp / L (SI kg / m 2 / s 2) is 0.082, 0.245, and 0.816, respectively, for a variety of nominal duct sizes. The three values chosen for friction loss correspond to, in US units inch water column per 100 feet, 0.01, .03, and 0.1.
The new flow rate, = + is the sum of the old flow rate and some change in flow rate such that the change in head over the loop is zero. The sum of the change in head over the new loop will then be Σ r ( Q 0 + Δ Q ) n = 0 {\displaystyle \Sigma r(Q_{0}+\Delta Q)^{n}=0} .
All parameters correctly handle plurals (1 win, 2 wins etc.). w - the number of wins; l - the number of losses; d - the number of draws; otl - the number of overtime losses; t - the number of ties (for use in sports, such as cricket, where draws and ties are different results)
In fluid dynamics, total dynamic head (TDH) is the work to be done by a pump, per unit weight, per unit volume of fluid. TDH is the total amount of system pressure, measured in feet, where water can flow through a system before gravity takes over, and is essential for pump specification.
The Prony equation (named after Gaspard de Prony) is a historically important equation in hydraulics, used to calculate the head loss due to friction within a given run of pipe. It is an empirical equation developed by Frenchman Gaspard de Prony in the 19th century:
For insurance, the loss ratio is the ratio of total losses incurred (paid and reserved) in claims plus adjustment expenses divided by the total premiums earned. [1] For example, if an insurance company pays $60 in claims for every $100 in collected premiums, then its loss ratio is 60% with a profit ratio/gross margin of 40% or $40.
