 Poster  Charisma Jankee (816007766) The University of the West Indies BSc ME with Biosystems Faculty of Engineering Department: Mechanical and Manufacturing Engineering MENG 3019 Poster Notes: Comparative efficiencies of horizontal versus vertical hydroponic plant growth systems. Background: The growing interest of hydroponic systems has immensely emerged in Trinidad and Tobago due to its popularity all over the world changing to a healthier consumption of crops. The hydroponic system is an efficient and effective resource management for the quality of food production. This project encompasses of the design, construction, and evaluation of a the NFT (nutrient film technique) of the vertical and horizontal system. Horizontal NFT hydroponic systems are better suited for large spaces which provide rapid yields for maximum plant growth. Whereas vertical NFT hydroponics is better suited for small spaces which provides rapid yields for maximum plant growth. Thus,...

Calculations - Average flow rate

Image
  Diameter of pipe, D = 4” = 0.1016 m R.T.F Volume flow rate   Flow rate = Area × Velocity   Velocity A pipe with an inner diameter of 4 inches contains water that flows at an average velocity of 2m/s   Volume flow rate = A × V                              = 0.0081 × 2                              = 0.0162 m 3 /s Converting seconds to hours Volume flow rate = 0.0162 × 3600 = 52.32 m 3 /hr

 The system was sent to Ms. Bharat for review and a problem arrived that the horizontal system build is incorrect. when the first system was build and approved she thought it was the vertical system. thus, a new horizontal system must be redesigned.

  On the lower end of the reservoir, a small tap was installed by firstly drilling a ½ inch hole into the reservoir, the tap was wrapped with thread seal then fastened with an adaptor that came with the tap. The edges of the reservoir were then layered with silicone to ensure that there were no leaks.   On the reservoir cover, a 3-inch square was cut using a sharp knife. Hinges were then used to create a hatch to monitor water level or add solution. A knob was attached to the hatch for easy access.   the system was then spray painted.

This is to connect the 4-inch T joint at the top of the bucket to the drainage pipe and flange inside the reservoir.  the grow tower was cut and an additional 4inch pipe with pockets were added to make them even.       Once the 4inch T joint is secured, on either side of the T joint, a 9 ½” length of 4-inch PVC is glued to the T joint to accommodate a 4-inch elbow on either side. The two plant towers can now be connected using PVC glue. the flange was attached and the pump line was tread inside using a string.    The pump’s outlet was routed to the top of the towers using water tubes. The water will flow down from a shower head, trickling down the top of the tower and back into the reservoir. The shower head was constructed by using a 4-inch PVC cap. The cap was placed on a round object and heated with the heat gun, creating a “belly”. On the cap, three rows of holes were drilled with a 1/16” drill bit around the circumference. At the centre of the sho...
