Answer the problem 1 

complete solution please thank youu

Considering all forms of energy flow into and out from the control volume with the mass, the - Em +gz pu++gz M. exits inlets h=u+pv but Q= Em +gz +gz +W exits inlets For a Unit Mass q=Eh++gz -Eh++gz +w exits inlets w = specific work Q= heat p= pressure v= specific volume v = velocity where g= acceleration due to gravity z = datum W = work This is the most frequently used form because many steady-flow systems have only one inlet and one exit. h+ +gz + W 2 exits inlets Q=mg(z, -z, )+÷m(v -v,?)+ ṁ(h, –h, ) + W Q-ΔΡE+ΔΚΕ + ΔΗ + W (9-4) For a Unit Mass q=g(z, -z, )+(v* -v;')+ (h, -h,. )+ w (9-5)
