'estimate_blended_head' takes a vector of transmissivity and a vector of hydraulic head and calculates the expected blended head for a cross-connected well. The length units for transmissivity and hydraulic head should be the same.

1	estimate_blended_head(transmissivity, head)

`transmissivity`	the transmissivity distribution for each interval
`head`	the head distribution for each interval

'estimate_blended_head' uses the following to calculate the blended head based on Sokol's 1963 equation 6:

h_{blended} = \frac{∑\limits_{i=1}^{N} T_i h_i}{∑\limits_{i=1}^{N} T_i}

where:

* h_{blended} is the blended head in the well * T_i is the transmissivity of the i^th interval * h_i is the formation head of the i^th interval * i is the interval number * N is the total number of intervals

a single value of the blended head
