Go Prestress Drop given Pressure after Immediate Loss

Δf Drop = (\frac{P o}{A Pre tension}) \cdot m Elastic

Go Modular Ratio given Prestress after Immediate Loss

m Elastic = Δf Drop \cdot \frac{A Pre tension}{P o}

Go Prestressing Force after Immediate Loss given Initial Prestress

P o = P i \cdot \frac{A Pre tension}{A Pretension}

Go Initial Prestress given Prestress after Immediate Loss

P i = P o \cdot \frac{A Pretension}{A Pre tension}
