Problem 1 Two nozzles having diameters of 4 in (10.16 cm) and 6 in (15.24 cm), respectively, discharge horizontally into the atmosphere with a velocity of 15 m/s. The water has a density of 1000 kg/m3. The axes of the 8-in (20.32 cm)-diameter pipe and both nozzles all lie in a horizontal plane. Use the Sl unit system to solve the problem. 4-in-dia jet R, 8 in Ry 6-in-dia jet The velocity of the water at the inlet of the 8 in. pipe, in m/s, is about: O 12 O 35 O 23 O 47 The x-component of the reactive force, R, in kN, on the left end of the 8 in. pipe is about : 350 170 976 O 720

The numerical value for the ideal mechanical advantage of a bicycle with 10 teeth on the effort gear and 40 teeth on the load.

Below question is from machine design. Please solve asap. You have to select bearings which are used to support a shaft, bearings are mounted at each end of shaft and 1.20 metre apart. A 600 mm diameter pulley is mounted at a distance of 300 mm to the right of left hand bearing and this drives a pulley directly below it with the help of belt having maximum tension of 2.25 kN. Another pulley 400 mm diameter is placed 200 mm to the left of right hand bearing and is driven with the help of electric motor and belt, which is placed horizontally to the right. The angle of contact for both pulleys is 180º and .Allowing working stress of shaft depends on the material you have selected for the shaft. Select the type of bearing mounted on both ends of shaft (either ball or roller bearing type and also elaborate the scenario for the selection of bearing).The Reliability Factor for Bearing may vary from 92% till 96%

Please provide Handwritten answer. show all tge steps and FBD. thank you:)
