Description

Basic calculations in hydroelectric power generation

Usage

P.hA(x)
P.Qh(x)
Pmax.Qh(x)
Pe.Pw(x)
Pmax.Qh.plot(x)
turbine.regions(type)
turbine.regions.all()
pipe.loss(pipe)

Arguments

x

a list with possible h, A, Q, nu, plab: head, cross-area, flow, efficiency,label

type

a turbine type from 'kaplan', 'francis', 'pelton', 'crossflow', 'slh'

pipe

Examples

# NOT RUN {
# head 3 m and cross-sectional area of 2 m2
x <- list(h=3,A=2); P.hA(x) 

x <- list(Q=1000,h=15); Pmax.Qh(x)

x <- list(Q=1000,h=15,nu=0.9); Pe.Pw(x)

x <- list(h=1,Q=100); P.Qh(x)

x <- list(Q=1000,h=15,plab="A"); Pmax.Qh.plot(x)
turbine.regions(type='francis')

x <- list(Q=0.01,d=0.075,L=200,mat='pvc')
hL <- pipe.loss(x)[1,1]
x <- list(h=30-hL,Q=0.01,nu=0.9)
P.Qh(x)
