$1k\frac{g}{h}$ of pure $H2SO4$ at $20C$ is mixed adiabatically with $5k\frac{g}{h}$ of pure $H20$ at $20C.$ What is the final temperature of the mixture? $($risposta: $T=50C)$

What is the thermal power required to bring the mixture defined above $($Q$1)$ at its boiling point? $($risposta: $P=360W)$

$3\mathrm{.}5kg$ of water solution of $H2SO4,$ at $40\%$ wt in acid at $90$ are mixed adiabatically with $2kg$ of solution at $80\%wt$ at $20C.$ Calculate the final $T$ of the mixture? $($risposta: $T=90C)$

$3\mathrm{.}5k\frac{g}{h}$ of water solution of $H2SO4,$ at $40\%$ wt in acid at $90C$ are mixed isothermically $($credo intenda isothermally$)$ with $2k\frac{g}{h}$ of solution at $80\%wt$ at $90C.$ Estimate the heat flow. $($risposta: $Q=-55$Kca$\frac{l}{h})$
