$********9\mathrm{.}3\mathrm{.}50.$ A boiler house flowsheet for a chemical process plant is shown in Eigure P$9\mathrm{.}3\mathrm{.}50$ on page ${594}_{?}.$ The production rate of $600$ psia superheated steam is $100,000l\frac{b}{h}r.$ The return condensate flow rate is $50,000l\frac{b}{h}r.$ Calculate:

a$.$ The flow rate of $30$ psia steam required in the deaerator $(l\frac{b}{h}r)$

b$.$ The flow rate of makeup feed water $(l\frac{b}{h}r)$

c$.$ The pump horsepower $($hp$)$

d$.$ The pump electrical consumption if the pump is $55\%$ efficient $(kW)$

e$.$ Yearly electrical cost to operate the pump $($at $\frac{0\mathrm{.}05}{k}Wh)$

f$.$ Yearly electrical savings if the pump could be operated with a $600$ psia discharge pressure

g$.$ Heat input to the steam drum $($Btu$/$hr$)$

h$.$ Heat input to the superheater section $($Btu$/$hr$)$

i$.$ The amount of $30$ psia steam lost to the atmosphere $(l\frac{b}{h}r)$

j$.$ The amount of $30$ psia condensate lost to the atmosphere $($lb$/$hr$)$
