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

The water (density =1000 kg/m3) leaves the nozzle (area of the nozzle=D0.01 m). Assuming steady, incompressible, and neglect the weight of jet and the plate, change in elevation is also neglected. Determine the horizontal reaction force (N) on the support. Note that the stagnation tube has a fluid of specific gravity S-10.4 and the deflection of the fluid in stagnation tube is 50 cm. stagnation tube angle-D40 deg T 50 cm Nozzle, angle =20 deg
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
Could you please spreate each question alone because there are two questions
Please the answer provided is not clear, some words and letters not clear, can you please type the answer or write clearly so that I can see

Please do the last three questions (2, 3 and 4)! Thank you in advance! A seesaw that weights 45lbs and its 5m long is balanced on the fulcrum in the center. 1- Two children are sitting on opposite sides of each other on the seesaw. One child weights 50lbs and is sitting 0.7m on the left end. Where should the other child sit in order to be balanced on the seesaw if they weigh 42lbs? 2- Now, a third child wants to sit on the seesaw and weighs 30lbs and is sitting 1.25m in front of them and is closer to the fulcrum on the right side. What are the CW and CCW moment of the seesaw now? What is the net moment and direction? 3- Then, a fourth child wants to play on the seesaw and is on the left side of the plank in order to bring the system to equilibrium. How much does the child weigh (Calculate the pounds of force needed in order for rebalance?) 4- Now the fourth child leaves the other three children sitting on the plank. If the three children are sitting in the same potions as they did…
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
