2.) Water from a stationary nozzle strikes a flat plate as shown below. The water leaves the nozzle at 15 m/s; the nozzle area is 0.01 m2. Assuming the water is directed normal to the plate, and flows along the plate, determine the horizontal for on the support. FLOW -Plate 6 NEPLE
Air flows into the atmosphere from a nozzle and strikes a vertical plate as shown in below figure. The reading on the pressure gage was 1.82 kPa. Determine the horizontal force required to hold the plate in place. Assume the flow to be incompressible and frictionless. Also consider the density of air is 1.23 kg/m² and neglect the air weight.

1 (a) A steady stream of water jet discharges from the nozzle with a uniform velocity of 10 m/s at angle 60° as shown in Figure 1. The jet strikes a horizontal plate 2 m above the nozzle exit. Upon impact, part of the flow is guided towards the left while the remainder towards the right, and the plate is suspended in the air. The weight of the plate is 25 N. Assume frictionless flow along the plate and weight...
III A horizontal 4-cm-diameter jet of water strikes a vertical plate. Determine the velocity issuing from the jet if a force of 700 N is needed to 1) Hold the plate stationary 2) Move the plate away from the jet at 8 m/s
Show all work and answer all parts of the problem please. The 45 degree elbow nozzle discharges water into the atmosphere. The cross-sectional area of the elbow is 25 cm2 150 cm2 at the inlet and 25 cm2 at the exit. Velocity at point 1 and 2 are given as 2 m/s and 12 m/s 450 respectively. The gage pressure at 1 is 73 kPa 150 em2 30 cm The elevation difference between the centers of the exit and the...
please show me how I can finds the answers of these two examples Example 1: Design of a Solar Heater (Black bodies: no convection) A square flat plate collector is exposed to solar radiation from both the sides. The exposed surface of the plate has an absorptivity of 1.0 for solar radiation. On a clear summer day on the earth's surface the solar radiation flux is approximately 1140 W/m2 and the surrounding air temperature is 25oC. Determine the surface temperature?...
Objective To determine the force generated by a jet of water striking on a surface Description of apparatus The supply is led to a vertical pipe terminating in a tapered nozzle. This produces a jet of water which impinges on the vane in the form of a Flat Plate, Hemispherical Cup, Conical Plate or 30° Angled Plate. The nozzle and vane are contained within a transparent cylinder; at the base of the cylinder there is an outlet by which the...
Homework 7 heat transfer 2018-20 1) A horizontal tube of 12.5-mm dimeter with an outer srface temperature of 240°C is placed in a room with an air temperature of 20°C. Estimate the heat transfer rate per unit length of the tube due to free convection. 2) Air at -10°C flows at 10 m/s over the roof plate of two 5m length rooms whose air is at Too-200C. The roof plate is 0.20-m thick concrete (k = 0.6 w/ m. K)....
14.13 (a) only Spreadsheet from HW 3: Manning: 1. Numerically solve for the normal depth using either MS-Excel or Matlab. Hint: your spreadsheet for critical depth in HW3 is a good place to start. 14.13 The channel in Problem 14.7 is excavated in smooth rock to a bed slope of 0.2%. Deter- mine the (a) normal depth of flow, (b) critical slope, and (c) state of flow in the channel. 14.7 A trapezoidal channel has a bed width of 3.5...
