Steam at a pressure of 6 MPa and a temperature of 500°C enters an adiabatic turbine with a velocity of 20 m/s and expands to a pressure of 50 kPa, and a dryness fraction of 0.98. The steam leaves with a velocity of 200 m/s. The turbine is required to develop 1MW. Determine: a) the mass flow rate of steam required, when KE is neglected, and b) What is the effect of KE on the answer? p= 6.0 MPa (257.64 deg-C) T V h 500 0.05665 3082.2 3422.2 6.8803 h, h, (kPa) (°C) (m³/kg) (m/kg) (kJ/kg) (kJ/kg) (kJ/kg.K) (kJ/kg.K) 100 99.63 0.00104 1.694 417.46 2,676 1.3026 7.3594

You are in an inventory management field these days. You are working for a place which works on 365 working days per year. The annual demand is 901 widgets per year. The ordering cost is $111 per order, regardless of size. The holding cost is $6 per widget per year. How many orders per year will you place? Please round your answer to the nearest integer.
I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5. 1 pass 2 fail 3 fail 4 pass

Question 20 Use basic drawing instruments (pencil, scale, protractor, compass, etc). The Front View of a line AB measures 65 mm and makes an angle of 45° with xy. A is in the H.P. and 15 mm in front of the V.P. The line is inclined at 30° to the V.P. Draw the projections of AB and find its true length and inclination with the H.P.

what will be the pressure gradient (kpa/m) at L=30 cm through the nozzle? At L=0, the liquid flows inside the nozzle has a specific gravity S=10.2, at L=0, the velocity is 2 m/s while at L=70 cm, the velocity is 6 m/s. Assume steady and inviscid flow. The velocity varies linearly with distance through the nozzle. 70 cm L 6 m/s 2 m/s 60 cm Liquid
