Answer:
Invitational Workshop
An invitational workshop is what many of us know. It’s what Lucy Calkins has made famous through the Reading and Writing Workshop. In the invitational workshop, the instructor usually hosts a minilesson. This minilesson is intended to meet the needs of the majority of children in the classroom. Afterward, the children are “invited” to employ the skills or strategy for the minilesson during workshop time, where students work independently or in small groups

Explanation:
Answer:
Enthalpy, hsteam = 2663.7 kJ/kg
Volume, Vsteam = 0.3598613 m^3 / kg
Density = 2.67 kg/ m^3
Explanation:
Mass of steam, m = 1 kg
Pressure of the steam, P = 0.5 MN/m^2
Dryness fraction, x = 0.96
At P = 0.5 MPa:
Tsat = 151.831°C
Vf = 0.00109255 m^3 / kg
Vg = 0.37481 m^3 / kg
hf = 640.09 kJ/kg
hg = 2748.1 kJ/kg
hfg = 2108 kJ/kg
The enthalpy can be given by the formula:
hsteam = hf + x * hfg
hsteam = 640.09 + ( 0.96 * 2108)
hsteam = 2663.7 kJ/kg
The volume of the steam can be given as:
Vsteam = Vf + x(Vg - Vf)
Vsteam = 0.00109255 + 0.96(0.37481 - 640.09)
Vsteam = 0.3598613 m^3 / kg
From the steam table, the density of the steam at a pressure of 0.5 MPa is 2.67 kg/ m^3

Diameter =
from continuity equation
![v_2 = [\frac{d_1}{d_2}]^2 v_1](https://tex.z-dn.net/?f=v_2%20%3D%20%5B%5Cfrac%7Bd_1%7D%7Bd_2%7D%5D%5E2%20v_1)
![= [\frac{0.200}{0.158}]^2 \times 100](https://tex.z-dn.net/?f=%3D%20%5B%5Cfrac%7B0.200%7D%7B0.158%7D%5D%5E2%20%5Ctimes%20100)
by energy flow equation
and q =0, w =0 for nozzle
therefore we have
but we know dh = Cp dt
hence our equation become
