are achieved, where [sigma] = 1 - [M.sup.2]/([L.sub.s] [L.sub.r]) is the leakage coefficient. Then (4) becomes
To analyze the effects of the leakage recharge of the aquifer on the initial dewatering of coalbed methane wells, the mathematical seepage model of water in the coalbed considering the aquifer leakage was established by using the leakage coefficient according to the unsteady seepage theory.
On the contrary, it is possible to stabilize the system by controlling the value of the leakage coefficient [30].
where [C.sub.em] is the external leakage coefficients of the motor and [C.sub.im] is the internal leakage coefficient of the motor.
where [Q.sub.1] is volume airflow rate ([m.sup.3]/s); [C.sub.l] is the leakage coefficient; [DELTA][p.sub.l] is the pressure difference across the leak (operative pressure difference of envelope, supply, and return duct system--l = e, s, r); and [n.sub.l] is the pressure exponent.
The leakage is modeled by the product of a constant leakage coefficient [K.sub.D] and the pressure p in the pressure pipe.
where [q.sub.s_b] is the flow rate which goes into the bore side of the arm cylinder from the SHT, [q.sub.s_r] represents the flow rate out from the rod side of the cylinder to the PHP, and [L.sub.ic] is the internal leakage coefficient of the arm cylinder.
A flow coefficient increase beyond 75% would represent an unrealistic leakage coefficient based on the data gathered from real buildings (Persily 1998).
Figures 6 through 8 investigate the effect of motor efficiency, the flank leakage coefficient, and the shell heat transfer coefficient on isentropic efficiency, volumetric efficiency, and compressor discharge temperature.
The performance of the EHA system can also be sensitive to variation within the system parameters of the working fluid such as variety of effective bulk modulus and the leakage coefficient due to changes in the working environment [5, 7, 9, 11-13].
[C.sub.i] = total leakage coefficient for wall or ceiling i
Each leakage location on a wall had the same leakage coefficient and exponent.
